75 V, 240 A — the rail switch that handles the surge
The IRFS7730TRL7PP: The 2 mOhm max on-resistance at 100 A, 10 V gate drive sets the conduction loss floor for a high-current rail — at 100 A the dissipation is just 20 W from Rds(on) alone, which the 375 W power rating can sink with adequate heatsinking.
Gate charge tells you what driver it needs
Total gate charge is 428 nC at 10 V. Input capacitance is 13970 pF at 25 V.
175°C junction — keeps running where others derate
The gate threshold voltage is 3.7 V max at 250 µA.
