Key Players
Competitive Landscape
Semiconductor device suppliers and Tier 1 automotive integrators compete across the EV power module value chain. Infineon Technologies, onsemi and STMicroelectronics control the largest SiC die supply positions, as Wolfspeed and ROHM Semiconductor invest in next-generation SiC MOSFET platforms. Module assembly specialists such as Semikron Danfoss and Tier 1 integrators including Bosch and Continental bring packaging and system-level expertise.
Infineon opened the world's largest 200 mm SiC fab in Kulim in August 2024, with EUR 2 billion phase-one investment and design contracts of about EUR 5 billion. In November 2025, Wolfspeed launched 1,200 V Gen 4 SiC six-pack modules with 22% lower on-resistance, targeting high-power EV inverters. In August 2025, Toshiba and BASiC Semiconductor formed a power module partnership that combines SiC and IGBT device technologies. Competition centres on wafer size migration, module thermal performance and direct OEM design-in relationships.

Approaches to the EV power module market diverge along the supply chain. Infineon and onsemi combine in-house SiC wafer growth with module assembly to control costs across the value chain. Wolfspeed supplies SiC substrates and bare die while also moving into packaged power modules, as shown by its own Gen 4 SiC six-pack module launch, placing it between pure device supply and system integration. Bosch and Continental approach the market as Tier 1 integrators, sourcing SiC and IGBT die from device makers and competing on inverter-level integration. The spectrum from vertical integration to specialised device or module supply shapes pricing and margin structures across the forecast period.
Who leads the EV power module market?
FMI estimates that Infineon Technologies holds a 20% to 25% share of the EV power module market, based on Infineon's SiC and IGBT module portfolio and design contracts across global OEMs. onsemi (15% to 20%), STMicroelectronics (12% to 16%) and Mitsubishi Electric (10% to 14%) follow. These estimates are derived primarily from public disclosures by non-Chinese suppliers and do not fully capture the scale of China-based module makers such as BYD Semiconductor and StarPower Semiconductor, which supply a China BEV market of 8.40 million units in 2025 -- a gap FMI flags for further primary research.
Which companies have the clearest recent product track record?
Infineon Technologies has documented over 10.5 million HybridPACK Drive module shipments since 2017 and a supply agreement with Rivian for the R2 platform. STMicroelectronics has qualified fourth-generation SiC MOSFETs at 750 V and has since qualified the 1,200 V variant as well. Wolfspeed is sampling 1,200 V SiC six-pack modules built on Gen 4 MOSFETs, with distribution planned for early 2026. ROHM's fourth-generation SiC MOSFETs have been adopted by Hitachi Astemo for EV traction inverters.
What should buyers evaluate before approving a supplier?
OEM procurement teams should assess wafer supply security (150 mm versus 200 mm SiC sourcing, substrate self-sufficiency), module qualification status (AEC-Q101, AQG 324), thermal performance at target junction temperatures, power cycling lifetime at operating temperature, design-in flexibility across 400 V, 800 V and 1,200 V platforms, and the supplier's ability to scale production volumes in line with vehicle launch timelines.
How is competition expected to change through 2036?
The transition from 150 mm to 200 mm SiC wafers will separate suppliers with internal wafer capability from those reliant on third-party substrate supply. Vertical integration across wafer, die and module production, as pursued by Infineon and onsemi, is expected to compress margins for smaller module assemblers. Tier 1 automotive integrators such as Bosch and Continental may consolidate module assembly closer to vehicle plants. Foundry-based SiC production, still a single-digit share of device revenue in 2024, could broaden access for module makers that lack in-house fabrication.
