Total gate charge is 17.7 nC at Vgs = 10 V, and input capacitance Ciss is 425 pF at Vds = 10 V. For a 100 kHz hard-switched converter, the gate drive power is roughly Qg × Vgs × fsw = 17.7 nC × 10 V × 100 kHz ≈ 18 mW — well within a standard gate-driver IC's capability. The low Qg relative to the 900 V class means the Miller plateau duration is short, which helps keep switching losses in check during turn-on and turn-off transitions. ## Thermal and mounting considerations The TO-220 package requires a heatsink for any continuous load above a few watts — the 110 W maximum dissipation at Tc = 25 °C drops to roughly 70 W at 100 °C case temperature, using the datasheet derating curve. Through-hole mounting with a screw or clip to the heatsink tab is standard; a thermal pad or grease between the tab and sink cuts the junction-to-case thermal resistance.
