Drive voltage is specified for both 4.5 V and 10 V; at 4.5 V the Rds(on) will be higher than the 5 mOhm at 10 V, so confirm the driver rail before committing the BOM. The 2 V threshold maximum at 27 µA ensures the part turns on cleanly with logic-level gate signals. ## Package and footprint — PG-TDSON-8-5 Supplied in the 8-lead PowerTDFN package (PG-TDSON-8-5), surface-mount with an exposed thermal pad. The package supports the 85 A drain rating when the pad is properly soldered to the PCB copper pour.","metaTitle":"Infineon BSC050N04LSGATMA1 OptiMOS N-Ch 40V 5mOhm MOSFET","metaDescription":"Infineon BSC050N04LSGATMA1 OptiMOS N-channel MOSFET, 40V, 5mOhm Rds(on) at 50A, 85A continuous drain, PG-TDSON-8-5 package.
