The 6.5 mOhm max on-resistance at 100 A, 10 V drive sets the conduction loss floor — at 100 A that is about 65 W of dissipation in the channel alone, so the 300 W package limit at Tc gives you headroom for switching losses. The gate charge is 93 nC at 10 V, which means a 100 kHz switching frequency draws roughly 9.3 mA from the gate driver — a standard 2 A driver handles it easily.
175 °C junction — fits the hot spots
It survives engine-bay ambient, downhole tool heat, or a crowded PSU enclosure without derating the current rating prematurely. The threshold voltage is 4 V max at 270 µA, so 8 V to 10 V drive is the sweet spot for minimum Rds(on).
TO-263-7 footprint — field-swap reality
The part comes in a TO-263-7 (D²Pak with 6 leads plus tab), surface-mount. The exposed tab is the drain — it needs a good thermal via array to the inner copper plane to hit the 300 W dissipation rating. On a site repair, you can swap it with a hot-air station or a soldering iron if the board has enough copper soak; orientation is obvious from the chamfered pin 1 corner.
