40 V, 120 A N-channel in the TO-262-3 I²Pak
It is housed in a PG-TO262-3 through-hole package (I²Pak, TO-262AA), which provides a lower thermal resistance path to the board than a TO-220 for the same die size, making it a common choice for high-current DC-DC converters, motor-drive bridges, and automotive power distribution.
Conduction and switching parametrics
Total gate charge is 176 nC at Vgs = 10 V, which means a gate-driver sourcing 1 A can switch the FET in about 176 ns; the 14000 pF input capacitance at Vds = 25 V confirms the driver must be sized for the Miller plateau region in hard-switched topologies. The maximum gate-source voltage is ±20 V, and the threshold voltage is 4 V at 140 µA drain current, so a 10 V gate drive is the recommended bias for minimum Rds(on) operation.
