800 V N-channel — the full-pack power switch for offline supplies
At 3.1 A drain current and 10 V gate drive, the Rds(on) is 1.5 Ohm maximum. Total gate charge is 46 nC at 10 V, so a 100 kHz switching frequency would draw about 4.6 mA from the gate driver — well within the capability of a standard MOSFET driver IC. Input capacitance is 1320 pF at 25 V drain-source, which influences the turn-on delay and the driver's peak current requirement.
Maximum power dissipation is 30 W at case temperature. For a repair tech, that means the heatsink needs to be sized for the actual load current and ambient, not the 6.2 A headline number.
