3 mOhm Rds(on) — conduction loss floor for high-current rails
That Rds(on) figure is the part's defining spec: in a 100 A continuous load, conduction loss sits at roughly 30 W before factoring in temperature derating.
Gate charge and driver budget
Gate charge is 198 nC at 10 V, with an input capacitance of 13000 pF at 60 V Vds. That Qg number sets the gate-driver peak current requirement: switching at 100 kHz with a 10 V drive swing, the average gate current is roughly 0.2 A, but the peak during the Miller plateau can exceed 2 A if the driver is sized for fast edges. A standard 1 A gate-driver IC will work at moderate frequencies; for hard-switching above 200 kHz, plan on a driver with 4 A or more peak capability to avoid excessive switching loss.
Package and thermal path
The PG-HSOF-8 (8-PowerSFN) surface-mount package uses a large exposed drain pad. Thermal resistance is split between the junction-to-ambient (3.8 W Ta) and junction-to-case (375 W Tc) ratings — the case figure is the one that matters when the pad is soldered to a copper plane. The package is MSL 3; bake before reflow if the moisture-barrier bag has been open longer than the floor-life window.
