FDN304P

UMW · MOSFETs · SOT-23

FDN304P from UMW, 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 G input GATE terminal of the P-channel MOSFET; gate-source voltage VGS is rated ±8V.
2 S passive SOURCE terminal of the P-channel MOSFET; the body diode continuous source-drain current IS is rated -1.2A and pulsed ISM is rated -10A.
3 D passive DRAIN terminal of the P-channel MOSFET; drain-source voltage VDS is rated -20V and continuous drain current ID is rated -2.4A.
