In a 40 V automotive or industrial power rail, this part keeps the I²R heat low enough that the TO-263-3 (D2Pak) footprint on a standard 2 oz copper board can dissipate 71 W at the case without forced air. ## Gate charge and drive sizing Gate charge Qg totals 43 nC at 10 V. For a 100 kHz switching stage, that works out to 4.3 mA average gate current — a standard 1 A driver has plenty of headroom. The input capacitance Ciss is 3440 pF at 25 V drain, which sets the Miller plateau timing; expect a few tens of nanoseconds of switching edge at moderate current. ## 175 °C junction — headroom for high-ambient environments Operating junction temperature spans -55 °C to 175 °C, 25 °C wider than the common 150 °C ceiling. That headroom matters for under-hood automotive or industrial enclosures where ambient hits 105 °C and the self-heating from 80 A peaks pushes die temperature. The threshold voltage Vgs(th) max is 4 V at 35 µA drain, which keeps it fully enhanced with a standard 10 V gate rail. ## Lifecycle and sourcing posture ROHS3 compliant. No official second-source or drop-in replacement is listed in the Infineon cross-reference for this order code.","metaTitle":"IPB80N04S404ATMA1 Infineon OptiMOS N-Ch 40V 80A MOSFET","metaDescription":"Infineon IPB80N04S404ATMA1 N-channel MOSFET, 40V drain-source, 80A continuous drain, 4.2 mOhm Rds(on) at 10V.
