650V CoolMOS™ CFD2
Balance between efficiency and robustness with fast body diode
CoolMOS™ CFD2 superjunction MOSFET family features MOSFETs with an integrated fast body diode. It is the ideal choice for high power applications such as in telecom and server markets, in which high efficiency levels need to be reached while not compromising on highest reliability and ease-of-use.
The CFD2 devices are the successor of 600V CFD with improved energy efficiency. It benefits from softer commutation behavior and therefore better EMI behavior. In addition, better light load efficiency, reduced gate charge, easy implementation and outstanding reliabilty complement the advantages of fast switching superjunction MOSFETs.
A recent trend in high power conversion is the move toward higher and higher power density. High power density can be achieved best by resonant switching topologies such as zero voltage or zero current switching, which enable higher efficiency by eliminating the turn-on losses.
The fast reverse recovery of CoolMOS™ CFD2 offers designers the benefits of
- Reduce stress on the device while body diode is not fully recovered and
- Extra safety margin for repetitive hard commutation in designs which translates into reduced design-in effort
