AEC-Q101 qualification and the -55 to 175 °C junction temperature range place it squarely in automotive under-hood and chassis-domain applications: engine management, electric power steering, DC-DC converters, and high-current load switching. ## 1.7 mOhm Rds(on) — conduction loss budget The 1.7 mOhm Rds(on) at 100 A and 10 V sets the conduction loss floor. The 158 W package power dissipation rating at case temperature requires adequate PCB copper area on the drain tab. ## Gate charge and switching speed Total gate charge is 190 nC at 10 V, with an input capacitance of 14560 pF at 25 V drain. The gate driver's supply decoupling must be sized for the charge transfer each cycle. ROHS3 compliant. No official successor or second-source cross-reference is listed — the part is sole-sourced to Infineon's OptiMOS line.","metaTitle":"IPB120N04S4L02ATMA1 Infineon OptiMOS N-Ch 40V 120A D2PAK","metaDescription":"Infineon IPB120N04S4L02ATMA1 N-channel MOSFET, 40V Vdss, 120A Id, 1.7mOhm Rds(on) at 10V.
