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.","metaTitle":"Infineon IPB120N10S403ATMA1 N-Channel MOSFET","metaDescription":"Infineon OptiMOS™ automotive N-channel MOSFET, 100V drain-source, 120A continuous drain, 3.5 mOhm Rds(on).
