Fairchild Supremos
Fairchild Semiconductor has unveiled its Supremos, a new generation of 600V Super-Junction Mosfets.
The combination of the Supremos' low RDS (ON) and total gate charge brings a 40 percent lower Figure of Merit (FOM) compared to Fairchild's 600V Superfet Mosfets.
These devices, the 165-milliohm-maximum FCP22N60N, FCPF22N60NT and FCA22N60N, and the 199-milliohm-maximum FCP16N60N and FCPF16N60NT, offer reverse recovery characteristics di/dt and dv/dt, ensuring higher reliability for resonant converter, LLC and phase-shifted full-bridge topologies found in switch-mode power supply (SMPS) designs.
Compared to Superfet Mosfets, the 600V Supremos offer a low gate charge for the same RDS(ON), delivering 20 per cent less switching and conduction losses.
They provide low input and output capacitances, improving efficiency at light load conditions.
These features enable power supplies to meet Energy Star 80 Plus Gold classification for desktop PCs and Platinum classification for servers.
