Power MOSFET with Industry-First 6.1 Milliohms On-Resistance in SO-8 Size Package
A power MOSFET with what is claimed to be the industry’s lowest on-resistance for a 60-V device in a package with double-sided cooling was released today by Vishay. The new SiE876DF, which comes in an SO-8 sized PolarPAK package, boasts maximum on-resistance of 6.1 milliohms at a 10-V gate drive, a 13 % improvement over the next best comparable device on the market.
Fairchild Semiconductor - Super-Junction MOSFETs
Fairchild Semiconductor 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.
