1200 Volt 175 Amp Wolfspeed WAS175M12BM3 Silicon Carbide Module with Normally Off Fail Safe Operation
Product Overview
The Wolfspeed WAS175M12BM3 is a 1200 V, 175 A Silicon Carbide Half-Bridge Module designed for high-frequency operation with ultra-low losses. It features zero reverse recovery from diodes and zero turn-off tail current from the MOSFET, offering normally-off, fail-safe device operation. The module boasts an industry-standard 62mm footprint, facilitating system retrofits and enabling increased system efficiency due to the low switching and conduction losses of SiC. It is suitable for demanding applications such as induction heating, motor drives, renewables, railway auxiliary & traction, EV fast charging, and UPS and SMPS.
