Infineon launches first 205°C SiC power module for EVs - Automotive World

Infineon has launched a 1300 V silicon carbide (SiC) power module for electric vehicle inverters, capable of continuous operation at 205°C—30°C higher than the industry standard of 175°C. This marks t... Read original →

Infineon’s 205°C, 1300V SiC module isn’t just a spec bump—it redefines EV inverter architecture. Thermally, it pressures cooling-system suppliers to innovate materials while accelerating adoption of >800V architectures, forcing gate drivers and MCUs to upgrade voltage tolerance. Regulatory-wise, it aligns with the EU Battery Regulation’s efficiency mandates but exposes supply chain fragility: high-purity SiC substrates remain dominated by U.S. and Japanese firms. Competitors will react swiftly—STMicroelectronics may fast-track its SiC JV with Sanan Optoelectronics in China, while Wolfspeed could slash prices to defend premium segments. Within 18 months, a de facto 'high-temp SiC' qualification standard will emerge; without breakthroughs in defect density control, suppliers from Taiwan, China and mainland China risk being confined to low-end inverters.
