Fairchild brings designers of power supplies, lighting, display and industrial applications a new generation of 600V Super-Junction MOSFETs — SupreMOS®. The combination of their low RDS(ON) and total gate charge brings a 40 percent lower Figure of Merit (FOM) compared to Fairchild's 600V SuperFET™ MOSFETs. In addition, the SupreMOS family offers a low gate charge for the same RDS(ON), providing excellent switching performance and delivering 20 percent less switching and conduction losses, resulting in higher efficiency. These features enable power supplies to meet ENERGY STAR® 80 PLUS Gold classification for desktop PCs and Platinum classification for servers.

These products are part of Fairchild's comprehensive portfolio of MOSFETs that offer designers a wide range of breakdown voltages (-500V to 1000V), state-of-the-art packaging and industry-leading FOM to deliver efficient power management anywhere electronic power conversion is needed.
