Automotive Power MOSFET Market: EV Power Electronics, 48V Architectures, and Automotive-Grade Switching Reshape Vehicle Electrical Design

The Global Automotive Power MOSFET Market was valued at USD 2.57 billion in 2025 and is projected to reach USD 4.43 billion by 2032, expanding at an 8.10% CAGR during the forecast period, according to analysis by Strategic Market Research.

 

The Automotive Power MOSFET Market is gaining importance as vehicles move from mechanical and relay-based control toward electronically switched, power-dense, software-managed electrical systems. Automotive MOSFETs are now used across body electronics, chassis systems, lighting, thermal management, electric pumps, fans, braking, steering, ADAS power control, battery management, onboard chargers, DC-DC converters, eAxles, traction inverters, and auxiliary power systems.

 

The market includes AEC-qualified silicon MOSFETs for 12V, 24V, and 48V systems, along with automotive SiC MOSFETs and SiC MOSFET modules used in high-voltage electrified platforms. This scope reflects how suppliers such as Infineon, Nexperia, STMicroelectronics, onsemi, ROHM, Wolfspeed, Mitsubishi Electric, Renesas, and Toshiba position their automotive power-device portfolios.

 

The base vehicle opportunity remains large. Global vehicle production reached 96.4 million units in 2025, up 3.9% from 2024, while global vehicle sales climbed to 99.8 million units, up 4.7%. This gives MOSFET suppliers a large production base even before EV-specific content is added. [OICA — Auto Industry Growth Shifted East in 2025 Amid Global Repositioning]

 

Content per vehicle is the more important story. Infineon states that a vehicle can use 100 to 180 power MOSFETs across about 90 applications, covering body, chassis, safety, ADAS, autonomous-driving systems, and powertrain. That means MOSFET demand is being shaped by the number of switching points inside each vehicle, not only by the number of vehicles produced.[Infineon — Automotive MOSFET]

 

EV Growth Is Increasing Power-Switching Content Per Vehicle

Electric vehicles carry more power electronics than conventional internal-combustion vehicles. Global electric car sales exceeded 20 million units in 2025, rising 20% from 2024 and reaching 25% of new car sales worldwide. The IEA also expects electric car sales to reach 23 million in 2026, equal to 28% of total car sales. [IEA — Global EV Outlook 2026 Executive Summary]

This matters directly for automotive power MOSFET demand because EVs need switching devices in onboard chargers, high-voltage DC-DC converters, battery management systems, thermal-management circuits, electric compressors, traction-related systems, power distribution units, low-voltage auxiliaries, and charging interfaces. Hybrids and plug-in hybrids add another layer of demand because they combine conventional vehicle electronics with electrified powertrain systems.

The number of electrified platforms is also widening. Nearly 1,000 electric car models were available globally in 2025, representing about 40% of roughly 2,500 car models worldwide. Electric model availability has more than doubled over the past five years. For MOSFET suppliers, this means more design-in opportunities across price segments, voltage classes, regional platforms, and vehicle architectures.

Silicon MOSFETs Remain Essential in 12V, 24V, and 48V Vehicles

SiC MOSFETs receive much of the attention in high-voltage EV discussions, but silicon MOSFETs remain deeply embedded across low- and mid-voltage vehicle systems. Most vehicles still operate large parts of their electrical architecture on 12V systems. Commercial vehicles and some heavy-duty platforms use 24V systems, while 48V architectures are expanding in mild hybrids, active chassis systems, electric turbocharging, pumps, fans, braking, steering, and high-current auxiliaries.

Infineon’s automotive MOSFET portfolio reflects this layered architecture. Its low-voltage automotive MOSFET range covers 12V and 48V board-net applications, with 55V–100V devices developed in OptiMOS 5 and OptiMOS 7, while its >48V portfolio includes 120V, 150V, and higher voltage automotive MOSFETs in robust leadless and leaded packages. [Infineon — Automotive MOSFET]

This voltage spread shows why the market should not be treated as an EV traction-inverter market alone. Silicon MOSFETs continue to serve body modules, lighting, HVAC, door and seat controls, wipers, pumps, motor drives, electronic fuses, power distribution, and chassis control. The growth of 48V systems gives these devices a longer runway because higher current loads require better switching efficiency, compact packaging, and stronger thermal handling.

 

SiC MOSFETs Are Moving Deeper Into xEV Power Platforms

SiC MOSFETs are gaining ground where automakers need higher efficiency, lower losses, smaller power-electronics systems, and better thermal performance. The strongest application areas are onboard chargers, traction inverters, high-voltage DC-DC converters, eAxles, and fast-charging-linked architectures.

Supplier activity shows how quickly this part of the market is moving. ROHM developed new 4-in-1 and 6-in-1 SiC molded modules in the HSDIP20 package for xEV onboard chargers, with six 750V models and seven 1200V models optimized for PFC and LLC converter circuits. [ROHM — ROHM Develops New High Power Density SiC Power Modules]

Mitsubishi Electric announced 5th-generation SiC-MOSFET bare die samples for EV, PHEV, and xEV drive-motor inverter and eAxle applications, with sample shipments planned from late June 2026. The company said the new devices achieve approximately 25% lower on-resistance than its existing 4th-generation trench SiC MOSFET products. [Mitsubishi Electric — Mitsubishi Electric to Ship 5th-generation SiC-MOSFET Bare Die Samples]

Wolfspeed introduced its Gen 5 SiC MOSFET technology in 2026, claiming up to 27% efficiency improvement over currently available competitive 1200V solutions and highlighting a qualified, ramp-ready 200 mm manufacturing platform for automotive and industrial customers. [Wolfspeed — Wolfspeed Announces Gen 5 Silicon Carbide Technology]

 

Charging Infrastructure Adds Pull-Through for EV Power Electronics

Public charging infrastructure is outside the vehicle, but it strengthens the same EV power-electronics ecosystem that supports onboard MOSFET demand. Global public charging points exceeded 7 million by the end of 2025 after nearly 1.8 million were added during the year, representing growth of more than 33% from the previous year.[IEA — Electric Vehicle Charging, Global EV Outlook 2026]

China remains the largest charging market, accounting for more than 65% of global public charging points. Its public charging network grew from nearly 3.4 million points at the end of 2024 to more than 4.7 million at the end of 2025, while fast and ultra-fast public chargers increased from 1.5 million to 2.2 million. In the United States, fast and ultra-fast public charging points grew 30% to nearly 70,000 in 2025. [IEA — Electric Vehicle Charging, Global EV Outlook 2026]

This matters for automotive MOSFET suppliers because charging infrastructure, onboard charging, DC-DC conversion, battery systems, and EV thermal systems are part of the same design conversation. Suppliers increasingly serve both vehicle and infrastructure customers with silicon MOSFETs, SiC MOSFETs, diodes, modules, gate-driver solutions, and thermal packages.

 

AEC Qualification and Long Supply Visibility Are Now Commercial Requirements

Automotive MOSFET selection is not a simple component-price decision. OEMs and Tier 1 suppliers need AEC qualification, production traceability, long-term availability, change-control discipline, package reliability, and stable wafer supply. Once a MOSFET is qualified into a vehicle program, changing the supplier or part number can require additional testing, redesign, and validation.

Nexperia states that its automotive portfolio includes fully qualified AEC-Q100/Q101 devices across energy- and design-efficient products, including automotive MOSFETs, logic, diodes, ESD protection, and other devices for connected, electric, and hybrid vehicles. [Nexperia — Automotive Applications]

Supply assurance has become a more visible part of the market after repeated semiconductor shortages and geopolitical disruptions. In May 2026, Polar Semiconductor and Nexperia announced a strategic collaboration to manufacture next-generation power MOSFETs at Polar’s U.S.-based wafer foundry. The partnership was positioned around expanded power MOSFET supply and global supply stability for automotive, robotics, industrial, and AI infrastructure customers. [Polar Semiconductor — Polar Semiconductor and Nexperia Partner on Power MOSFET Manufacturing]

 

Thermal Packaging Is Becoming a Design-Level Differentiator

As vehicles add more electrical loads, MOSFET packaging has become more important. Higher current density, smaller control units, under-hood heat, EV power modules, battery systems, and 48V loads all create thermal pressure. A MOSFET with strong electrical performance can still become difficult to design in if the package does not support heat removal, compact layout, and reliable operation.

onsemi launched EliteSiC MOSFETs in the industry-standard T2PAK top-cool package in December 2025, positioning the package for improved thermal performance, reliability, and design flexibility in EVs, solar infrastructure, and energy storage systems.[ onsemi — onsemi Launches New Cooling Packaging Technology to Drive Efficiency in Power-Hungry Applications]

Infineon also highlights a broad automotive MOSFET package range across 12V, 24V, 48V, and >48V board-net applications, including robust leadless and leaded packages such as TOLL, TOLG, and TOLT for high-current capability. [Infineon — Automotive MOSFET]

 

China Is the Largest Demand Pool for EV-Linked Automotive MOSFETs

China is the most important regional market for EV-linked automotive MOSFET demand. More than 13 million electric cars were sold in China in 2025, accounting for six out of ten electric cars sold globally. Electric vehicles represented almost 55% of new car sales in China, and by the end of 2025, China had an estimated 44 million electric cars on the road, representing around 13% of the country’s car stock. [IEA — Trends in Electric Cars, Global EV Outlook 2026]

The country also has the strongest electric model availability. In 2025, China had more than 1,100 car models available, with nearly 700 electric models. Electric models outnumbered conventional models, making China the only major automotive market where this was the case. This matters for MOSFET suppliers because the number of platforms, trims, price points, and battery-electric architectures directly increases the number of design-in opportunities. [IEA — Trends in Electric Cars, Global EV Outlook 2026]

China’s vehicle and charging ecosystem also supports the wider power semiconductor base. The country produced and sold large volumes of EVs, led global public charging deployment, and accounted for the majority of global EV sales. Automotive MOSFET suppliers serving China need broad voltage coverage, price competitiveness, strong thermal packaging, and local customer support because design cycles are fast and platform turnover is high.

 

Europe Remains a High-Value xEV and Power-Electronics Region

Europe remains a major region for automotive MOSFET design-in because of strong electrification policy, premium vehicle content, Tier 1 supplier depth, and powertrain engineering capability. Electric car sales in Europe increased by more than 30% in 2025 to 4.2 million units, equal to 28% of new-car sales. The European Union sold almost 3 million electric cars, with EV share just under 27%. [IEA — Trends in Electric Cars, Global EV Outlook 2026]

Germany remains especially relevant. Electric car sales in Germany increased by 50% in 2025 to a record 850,000 units, and around 30% of cars sold in Germany were electric. The United Kingdom also saw electric car sales increase by more than 25%, with electric vehicles accounting for more than one in three new cars sold. [IEA — Trends in Electric Cars, Global EV Outlook 2026]

For automotive MOSFET suppliers, Europe is important not only because of EV sales but also because platform engineering decisions are often made in the region. Suppliers such as Infineon, STMicroelectronics, Nexperia, and major Tier 1s influence the selection of devices used in 12V, 48V, onboard charging, battery, chassis, powertrain, and safety systems. European buyers tend to place strong emphasis on qualification, efficiency, reliability, and long-term product support.

 

North America Remains Material, but EV Demand Is More Uneven

North America remains an important automotive power semiconductor market, but EV-linked MOSFET demand is less uniform than in China and Europe. U.S. electric car sales were around 1.5 million units in 2025, slightly lower than in 2024. Electric vehicles represented around 10% of U.S. car sales for the full year, but fourth-quarter EV sales were 45% lower than in the same period of 2024 after policy changes and the ending of tax credits. [IEA — Trends in Electric Cars, Global EV Outlook 2026]

That uneven EV demand does not remove the region’s relevance. North America still has high-value vehicle platforms, pickup and SUV electrification, 48V adoption potential, charging infrastructure investment, semiconductor localization, and strong demand from automotive, industrial, aerospace, and defense-related electronics. The Polar Semiconductor-Nexperia manufacturing partnership also supports the region’s role in power MOSFET supply resilience. [Polar Semiconductor — Polar Semiconductor and Nexperia Partner on Power MOSFET Manufacturing]

 

Supplier Strategies Are Moving Closer to Vehicle Platform Design

The Automotive Power MOSFET Market is no longer led only by catalog expansion. Suppliers are trying to fit more closely into platform decisions made by OEMs and Tier 1s. That means offering devices that match specific voltage architectures, thermal layouts, package constraints, qualification requirements, and long vehicle production schedules.

Infineon is positioned across low-voltage and high-voltage automotive MOSFETs, with coverage from 12V and 48V board-net applications to >48V applications using 120V, 150V, and higher voltage devices. Nexperia is emphasizing AEC-qualified automotive devices and supply stability through its U.S. foundry partnership with Polar. ROHM is targeting xEV onboard chargers with compact 750V and 1200V SiC modules. Mitsubishi Electric is pushing SiC bare dies for EV inverters and eAxles. Wolfspeed is emphasizing next-generation 1200V SiC efficiency and 200 mm manufacturing readiness. onsemi is focusing on thermal packaging for compact, cooler, higher-efficiency systems. [Infineon — Automotive MOSFET | Nexperia — Automotive Applications | ROHM — ROHM Develops New High Power Density SiC Power Modules | Mitsubishi Electric — 5th-generation SiC-MOSFET Bare Die Samples | Wolfspeed — Gen 5 Silicon Carbide Technology | onsemi — New Cooling Packaging Technology]

For OEM and Tier 1 sourcing teams, the shortlist is usually built around practical design questions: Can the device handle the voltage class? Does the package fit the board and cooling approach? Is the part AEC-qualified? Will the supplier support the program for years? Can the supplier maintain stable supply across regions? Will the device help reduce power loss without adding packaging complexity? These questions are influencing supplier selection more than broad portfolio size alone.

 

Analyst Insight

The Automotive Power MOSFET Market is expanding because vehicles are becoming electrically denser. Global vehicle production gives the category scale, but electrification, 48V systems, ADAS, body electronics, battery management, onboard charging, DC-DC conversion, thermal management, eAxles, and software-controlled power distribution are increasing MOSFET content per vehicle.

Silicon MOSFETs will continue to serve the large base of 12V, 24V, and 48V applications across ICE, hybrid, and EV platforms. SiC MOSFETs will gain share in high-voltage xEV applications where efficiency, range, heat, compactness, and charging performance carry more weight. The market is not moving from silicon to SiC in a straight line. It is splitting into two durable opportunity pools: high-volume low-voltage switching and high-value high-voltage power conversion.

The suppliers best placed in this market will be those that can combine automotive qualification, voltage coverage, thermal packaging, long product availability, and stable manufacturing support. For automakers, MOSFET sourcing has become part of platform reliability and power-electronics planning, not just a component-purchasing exercise.
