Infineon’s answer to resonant high power topologies The 600 V CoolMOS™ CFD7 SJ MOSFET is Infineon’s high voltage superjunction MOSFET technology with an integrated fast body diode, completing the CoolMOS™ 7 series. The CFD7 is the successor to the CoolMOS™ CFD2 SJ MOSFET family and comes with a reduced gate charge (Qg), improved turn-off behavior, and a reverse recovery charge (Qrr) of up to 69% lower compared to the competition, as well as the lowest reverse recovery time (trr) in the market.
