Wolfspeed Unveils the Industry’s Lowest RDS(ON) Silicon Carbide (SiC) MOSFETs in New Technology Generation - New Castle News

Wolfspeed has unveiled its fifth-generation silicon carbide (SiC) MOSFETs, delivering industry-leading performance with the lowest RDS(ON) values to date. Targeted at 1200V and 750V automotive and ind... Read original →

Wolfspeed’s Gen-5 SiC MOSFETs, with 27% lower specific on-resistance (RSP), redefine power density limits—enabling smaller, cooler traction inverters and accelerating 800V architecture adoption beyond premium EVs. Technically, reliance on mature 200mm fabs sidesteps EUV export controls but intensifies thermal and packaging demands upstream. Geopolitically, U.S. CHIPS Act incentives bolster Wolfspeed’s domestic capacity in North Carolina, yet non-U.S. automakers may face higher costs amid tightening tech controls. Competitors like Infineon, ROHM, and STMicroelectronics will likely counter with co-developed automotive modules or hybrid Si/SiC solutions to delay full SiC transition. Within 18 months, this device will become the de facto standard for high-efficiency e-drives and trigger stricter industrial power supply regulations—where efficiency isn’t just optimal, it’s mandatory.
