Wolfspeed expands C3M SiC MOSFET Platform to 1200V

Cree owned Silicon Carbide power semiconductor maker Wolfspeed has expanded its innovative C3M platform through the introduction of a 1200V, 75 Milli ohms MOSFET in its recently released low-inductance discrete packaging helping powersupply design engineers to achieve 99 percent efficiency levels in three-phase power factor correction circuits. Wolfspeed said this MOSFET enables designers of applications such as telecom power supplies, elevators, grid-tied storage, on and offboard EV charging, as well as factory automation to increase switching frequency while maintaining efficiency, decreasing system size and bill of materials. “We are very encouraged about the new SiC products being introduced in new innovative discrete packaging,” said Kurt Goepfrich, a Siemens hardware architect. “These new package options, such as the surface-mount 7L D2PAK, allow us to explore new topologies not possible with existing products available on the market today.” Wolfspeed claims this device achieves the industry’s lowest figure-of-merit for any SiC MOSFET at 1200V. Wolfspeed has released this device in a 4L TO-247 package and plans to release it in a 7L D2PAK in the coming weeks. “SiC MOSFETs have proven to be beneficial for many high-power applications connected to a battery simply due to the improved efficiency.” explains John Palmour, Wolfspeed’s CTO. “In the case where power ...
