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

Wolfspeed has unveiled its fifth-generation silicon carbide (SiC) MOSFET technology, achieving the industry's lowest RDS(ON) performance for 1200V and 750V automotive and industrial applications. This... Read original →

Wolfspeed’s Gen 5 SiC MOSFETs, achieving record-low RDS(ON), directly tackle power density limits in EV traction inverters and fast chargers, accelerating adoption of 800V architectures beyond premium segments. Technically, the 200mm-compatible process eases customer migration but pressures upstream substrate suppliers to tighten defect control. Downstream, OBC and DC-DC designs will shift toward higher switching frequencies. Geopolitically, while U.S. CHIPS Act incentives favor domestic SiC scaling, non-U.S. automakers face rising supply chain scrutiny. Against STMicroelectronics’ and Infineon’s mature 1200V offerings, Wolfspeed is racing to define the next platform—especially as AI data centers drive industrial SiC demand. If yield ramps hold over the next 18 months, rivals may be forced into premature Gen 4+ transitions or risk permanent cost disadvantage.
