Gate charge and switching budget
Total gate charge is 34 nC at 10 V. For a 100 kHz switching frequency, the average gate-drive current needed is 3.4 mA, well within the capability of a standard MOSFET driver. The 2800 pF input capacitance at 20 V drain-source helps estimate the switching loss: the driver must charge and discharge this capacitance each cycle, so higher frequencies increase the driver's power dissipation.
175°C junction — high-temp margin
The 4 V maximum gate threshold at 200 µA drain current ensures the device turns on fully with a standard 10 V gate drive, even at elevated temperature where Vgs(th) drops.
Through-hole TO-220 — thermal and mechanical fit
The PG-TO220-3 package (standard TO-220 outline) mounts through a single hole in the PCB or heatsink, with the tab soldered to the copper island for thermal transfer. The 68 W power dissipation at case temperature assumes the tab is bolted to an infinite heatsink; in practice, derate according to the thermal resistance junction-to-case (not listed here, but typical for TO-220 is ~1–2 °C/W).
