LPM3401B3F

LOWPOWER · MOSFETs · SOT-23

LPM3401B3F from LOWPOWER, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Gate input Gate pin of the P-channel MOSFET; the datasheet limits the gate-source voltage VGS to ±12 V.
2 Source passive Source pin of the P-channel MOSFET; the drain-source voltage VDS is rated at -15 V.
3 Drain passive Drain pin of the P-channel MOSFET; continuous drain current is rated at -4 A at TA=25°C.
