Industry-leading Figures of Merit (FoM)

Figure-of-Merit (FoM) comparisons are critical for power designers to identify the best technology for their design, not merely based on a specific product spec, but by comparing performance widely across a variety of topologies, power levels, etc.

The UnitedSiC (now Qorvo) high-performance Gen 4 series deliver lower conduction loss, simple gate driving, and reduced switching losses in hard and soft-switched circuits compared to competing SiC FET devices.
