It handles 100 A continuous at the case temperature, making it a fit for high-current switching in automotive and industrial power stages — motor drives, battery management, and DC-DC converters. The PG-TDSON-8-1 package (8-PowerTDFN) is a surface-mount footprint common in compact power layouts. ## Key ratings for the BOM decision The 100 A continuous drain rating at case temperature is package-limited — in practice, the 2.5 W at ambient and 83 W at case dissipation limits tell you the real current depends on heatsinking. On a typical PCB without a heatsink, you are derated well below 100 A; with a good thermal path to a copper plane or external heatsink, it can deliver. For production BOMs, this means no near-term obsolescence risk.","metaTitle":"Infineon BSC030N04NSGATMA1 N-Channel MOSFET, 40V, 3mOhm","metaDescription":"Infineon OptiMOS N-channel MOSFET, 40V Vdss, 3mOhm Rds(on) at 50A, 100A continuous.

The part is active, so no successor has been designated. For a pin-compatible alternative within the same function class, compare other 40 V N-channel OptiMOS parts in the PG-TDSON-8-1 package — the BSC030N04NSG is the 3 mOhm variant; a higher Rds(on) sibling like BSC060N04NSG would trade higher resistance for lower gate charge."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BSC030N04NSGATMA1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BSC030N04NSGATMA1 when reusing this data.
