The 500 V drain-source breakdown voltage and 7 A continuous drain current define the application headroom for offline flyback converters, PFC stages, and similar topologies. Gate charge is 17 nC at 10 V, so the drive circuit sees a moderate load; a substitute with significantly higher Qg may require a stronger gate driver. Input capacitance is 450 pF at 50 V, which influences switching losses and turn-on delay.
