OptiMOS N-channel for 25 V rails
The Infineon BSC026NE2LS5ATMA1 is an N-channel MOSFET from the OptiMOS series, rated for a drain-source voltage of 25 V and a continuous drain current of 24 A at ambient temperature (Ta) or 82 A when the case temperature (Tc) is held at 25°C. The 2.6 mOhm maximum on-resistance at 10 V gate drive keeps conduction losses low in synchronous rectification, load switches, and DC-DC converters. The PG-TDSON-8-7 package (8-PowerTDFN) is a surface-mount can with an exposed drain pad for thermal transfer to the PCB.
What the key ratings mean for your BOM
The dual current rating (24 A at Ta, 82 A at Tc) is the thermal boundary: 24 A is what the part can carry on a standard FR4 board with no forced airflow; 82 A requires the case held at 25°C, which means a heatsink or substantial board copper tied to the drain pad. For most designs, the real limit is somewhere between — budget the thermal resistance and ambient temperature to find your actual derated current.
Lifecycle and compliance
ROHS3 compliant. The -55 to 150°C junction temperature range covers industrial and automotive under-hood environments. No AEC-Q101 qualification is stated in the listing, so verify with the full datasheet if automotive-grade is required.
