100 A continuous drain — what it buys the power stage
That current rating is the headline number for motor-drive output stages, battery-management disconnect switches, and DC-DC converter primary-side FETs where the load pulls tens of amps and the bus voltage stays under 48 V. That low Rds(on) keeps conduction losses under 23 W at 50 A — manageable for a TO-262 package bolted to a heatsink, but the 156 W case-temperature power dissipation limit means the thermal design has to move that heat into a metal substrate or forced air.
Gate charge and switching — 133 nC at 10 V
That gate charge figure is moderate for a 100 A FET — the driver needs to source about 1.33 A to hit a 100 ns rise time at 100 kHz switching frequency.
Through-hole TO-262 — field-swappable without a hot-air station
The TO-262-3 (I²Pak) package, also known as TO-262AA, is a through-hole variant of the D²Pak with long leads. It bolts directly to a heatsink through the tab hole and solders into the board — no reflow profile, no hot-air station.
