Infineon Technologies · MOSFET, N-channel · PG-TDSON-8 FL (5 x 6 mm)
Infineon BSC014N04LSIATMA1 (type BSC014N04LSI): an OptiMOS N-channel power MOSFET, 40 V, 1.45 mOhm maximum at 10 V gate drive, logic-level, in the PG-TDSON-8 FL (SuperSO8, 5 x 6 mm) package with an exposed drain pad. Marked 014N04LI on the part.
Note: Datasheet and symbol name the drain as pin 5 with pins 5 to 8 and the exposed pad joined. The KiCad TDSON-8-1 footprint carries the drain pads as number 5.
Verification
A person checks each page against its datasheet and signs it off here; the badge turns amber if a checked file changes.
