Junction temperature and switching budget
The 37 nC total gate charge at 10 V means a 1 A gate driver can switch this FET at roughly 27 kHz before the average gate-drive current hits 1 A — a practical ceiling for hard-switched topologies. Input capacitance is 920 pF at 25 V drain bias. That capacitance, combined with the gate-drive source impedance, sets the turn-on and turn-off delay; a 10 Ω gate resistor and a 1 A driver yields a ~10 ns rise time, which keeps switching losses manageable up to 100 kHz in a clamped-inductive load.
Through-hole TO-220AB — heatsink-ready
The TO-220AB package (TO-220-3) is a through-hole, single-gauge tab with a mounting hole for a screw-on heatsink. The 70 W maximum power dissipation at case temperature assumes the tab is bolted to an infinite heatsink — real-world derating follows the junction-to-case thermal resistance, which the datasheet's thermal curves provide.
