Third-Generation SiC MOSFET Platform expanded to 1200V

Wolfspeed, a Cree Company and a leader in silicon carbide (SiC) power products, has expanded its innovative C3M™ platform through the introduction of a 1200V, 75mΩ MOSFET in its recently released low-inductance discrete packaging. The new device simplifies designs and enables an increase in frequency while maintaining efficiency, lowering system cost, reducing circuit EMI, and enabling 99% efficiency levels in three-phase power factor correction circuits.

These features enable 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.
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 is bidirectional, such as grid-connected AC-DC, the potential cost savings are significantly increased due to the reduction in the size of the input filter.”
