Automotive-grade power switch for high-current loads
It comes in a PG-TO263-3 (D²PAK) surface-mount package and carries AEC-Q101 automotive qualification, making it a fit for under-hood power distribution, motor-drive bridges, and DC-DC converter stages where high current and thermal cycling are the norm.
3.5 mOhm Rds(on) — conduction loss floor at 100 A
Maximum on-resistance is 3.5 mOhm at a 100 A drain current with 10 V gate drive. That figure is specified at 25°C junction — expect it to roughly double at 175°C, so the thermal design should budget for ~7 mOhm hot resistance. The 140 nC total gate charge at 10 V means a gate driver capable of sourcing at least 1.4 A peak is needed to hit a 100 ns switching edge; a weaker driver stretches the switching loss window.
175°C junction rating — thermal headroom for harsh environments
Operating junction temperature spans -55°C to 175°C, which covers the full automotive temperature grade 0 range. The 250 W power dissipation at case temperature is a theoretical maximum — real-world dissipation is limited by the PCB copper area under the D²PAK tab and the airflow. A 10120 pF input capacitance at 25 V drain-source sets the switching energy; the gate drive loop inductance needs to be kept under 10 nH to avoid ringing at turn-on.
