6.6 mOhm at 10V — the conduction-loss floor for a 200V switch
The headline figure is the 6.6 mOhm max on-resistance at 10V gate drive and 82A — this sets the I²R conduction loss that determines the heatsink size and the PCB copper pour for the TO-247AC tab.
203 nC gate charge and the gate-driver budget
Total gate charge at 10V is 203 nC, with an input capacitance of 9820 pF at 50V drain. For a 100 kHz switching frequency, the average gate-drive current needed is 20.3 mA; the peak current is set by the driver's source/sink capability and the external gate resistor. The ±20V Vgs(max) rating gives headroom for a 12V or 15V gate drive without clamping.
175°C junction — the thermal design target
Power dissipation is rated 556W at Tc=25°C. The TO-247AC package's large tab area and isolated mounting hole simplify direct heatsink attachment — the thermal resistance from junction to case is the limiting factor, not the plastic body.
ROHS3 compliant. For a production BOM, this means no supply-risk flag from imminent obsolescence.
