What this part is and where it fits
The Infineon BSC009NE2LSATMA1 is an N-channel power MOSFET from the OptiMOS series, built for low-voltage, high-current switching. It handles a 25 V drain-to-source voltage and delivers up to 100 A continuous drain current when the case is held at 25 °C — the 41 A Ta rating is the free-air limit, so plan on a heatsink or PCB copper pour to reach the full capability. The 0.9 mOhm maximum on-resistance at 30 A and 10 V gate drive keeps conduction losses low in synchronous rectification, DC-DC converter output stages, and battery-protection circuits. The PG-TDSON-8-7 package (8-PowerTDFN) is a surface-mount footprint with an exposed pad for thermal transfer to the board.
Lifecycle and compliance
ROHS3 compliant, no exemptions needed. The junction temperature range of -55°C to 150°C covers automotive under-hood and industrial motor-drive environments.
