Product details

Gate charge and switching loss budget

The IPB120N04S402ATMA1 total gate charge is 134 nC at 10 V, which sizes the gate-drive current for a target switching frequency.

Temperature range and package reality

Junction temperature spans -55 °C to 175 °C, extending the safe operating area into engine-bay, downhole, or high-density power stages where ambient heat soaks the junction. The D2PAK (TO-263) footprint with a large copper pad on the PCB is required to pull the 158 W power dissipation away from the die — a two-layer board with limited copper will throttle the current rating.

Frequently asked questions

What is the Rds(on) of IPB120N04S402ATMA1?
