BSS308PE

UMW · MOSFETs · SOT-23

BSS308PE 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; the datasheet states the device operates with gate voltages as low as 2.5V and the gate-source voltage is rated at ±20V.
2 S passive SOURCE terminal of the P-channel MOSFET, part of the device rated at VDS = -30V.
3 D passive DRAIN terminal of the P-channel MOSFET; the datasheet rates continuous drain current ID at -2 A at TA=25°C.
