Wolfspeed’s CAS480M12HM3

Wolfspeed has developed the HM power module platform to provide the benefits of SiC in power density sensitive applications, while maintaining the baseplate compatibility of a 62mm module. The HM platform’s SiC optimized packaging enables 175°C continuous junction operation, with a high-reliability Silicon Nitride (Si3N4) power substrate to ensure mechanical robustness under extreme conditions and a lightweight AlSiC baseplate. The HM3 is a perfect fit for demanding applications such as medical power supplies, aerospace, and traction drives.

The CAS480M12HM3 is a 1200 V, 480 A all-SiC, high-performance, switching-optimized, half-bridge module.
