For a synchronous buck converter or a motor-drive H-bridge, that 2.2 mOhm floor translates directly into conduction loss: at 50 A, the I²R dissipation sits at roughly 5.5 W, well within the 167 W package limit. ## 175 °C junction — headroom for harsh environments That extra 25 °C matters in under-hood automotive, industrial motor compartments, or downhole tools where the ambient near the heatsink can push junction spikes past 150 °C. ## Gate charge and input capacitance — the driver budget Total gate charge Qg is 166 nC at Vgs = 10 V, with an input capacitance Ciss of 13000 pF at Vds = 20 V. A 166 nC gate charge at a 100 kHz switching frequency draws 16.6 mA average from the gate driver — a standard 2 A gate-driver IC handles that comfortably, but the 13 nF input capacitance means the driver must source a peak current of several amps during the Miller plateau transition. The PG-TO263-3-2 package (D²Pak) exposes a large copper tab on the bottom for heatsinking; the thermal pad area on the PCB sets the effective RthJA. ## Active lifecycle and compliance It carries ROHS3 compliance, meaning no restricted phthalates or halogenated flame retardants in the package. The series is OptiMOS™ 3, a mature 40 V trench-technology node that has been in volume production for years; the date-code traceability from Infineon's fabs is well-documented, and the laser-etched markings on the TO-263 body are consistent across production lots — a useful check when vetting independent-distributor stock.","metaTitle":"Infineon IPB022N04LG N-Channel MOSFET, 40 V, 2.2 mOhm","metaDescription":"Infineon IPB022N04LG OptiMOS™ 3 N-channel MOSFET, 40 V, 90 A, 2.2 mOhm Rds(on) at 10 V.
