Wolfspeed - Introduces Fifth-Generation Sic Mosfets For 1200 V And 750 V Applications - TradingView

Wolfspeed has introduced its fifth-generation silicon carbide (SiC) MOSFETs designed for 1200V and 750V applications, marking a significant advancement in power semiconductor technology. These devices... Read original →

Wolfspeed’s fifth-gen SiC MOSFETs aren’t just incremental—they’re forcing a full-stack recalibration across power electronics. By targeting 750V/1200V applications in EV traction and solar inverters, they accelerate the obsolescence of silicon IGBTs. Upstream, substrate suppliers face tighter specs on crystal quality and wafer size; downstream, module designers must tackle EMI from higher switching frequencies. While Wolfspeed’s in-house 8-inch fab mitigates U.S.-EU supply chain anxieties, its capex surge pressures near-term margins. Competitors like Infineon and STMicro will likely double down on OEM partnerships and IDM integration, while emerging players in Taiwan, China and mainland China may undercut on industrial-grade volumes. Over the next 18 months, 800V EV architectures will drive SiC adoption—but yield curves and substrate shortages will dictate who controls pricing power.
