62 mm BM3 Silicon Carbide Half-Bridge Power Modules

62 mm BM3 Silicon Carbide Half-Bridge Power Modules

Wolfspeed’s BM3 power module platform provides the system benefits of Silicon Carbide (SiC) while maintaining the robust, industry-standard 62 mm module package. The internal design of Wolfspeed’s 62 mm BM3 package enables high speed Silicon Carbide switching benefits and increased system efficiency, due to the low-inductance layout.

The BM3 platform is a perfect fit for high frequency industrial applications such as induction heating, rail and traction, motor drives, and EV charging infrastructures.
