Silicon, GaN, or SiC? Choosing the Right Power Technology

Designers today must balance efficiency, robustness, cost, and design complexity when choosing between silicon MOSFETs, GaN, and SiC.

SuperQ™ MOSFETs redefine those tradeoffs — delivering performance that challenges wide-bandgap devices without abandoning the simplicity of silicon.

SuperQ™ A New Position on the Power Technology Map

Category	Silicon MOSFETs	SuperQ™	GaN	SiC
