The IRF9321TRPBF: Total gate charge is 98 nC at 10 V. The drive voltage range spans 4.5 V to 10 V.
The junction temperature range covers -55°C to 150°C, which qualifies the part for military, avionics, and downhole auxiliary power switching — not just industrial. The 2.5 W maximum power dissipation at 25°C ambient in the SO-8 package limits continuous current in still air; a 1 oz copper pad on the PCB drops the thermal resistance.
At 4.5 V gate drive the on-resistance is higher — check the typical curve in the datasheet for the exact value at your operating point.
