The TO-220AB through-hole package keeps the thermal path short: 330 W maximum power dissipation at the case, with the junction rated to 175 °C.
Total gate charge is 230 nC at 10 V. The 5110 pF input capacitance at 25 V drain-source gives a rough handle on the driver's sourcing and sinking capability — a gate resistor in the 5–10 Ohm range keeps the ringing under control without stretching the switching loss window.
This is the worst-case figure at 25 °C junction; actual Rds(on) rises with temperature per the normalised curve in the datasheet.
The input capacitance is 5110 pF at 25 V drain-source. These numbers set the gate-driver peak current requirement for the target switching frequency.
