WM02N31M

Wayon · MOSFETs · SOT-23

WM02N31M from Wayon, 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; controls the channel, with VGS rated ±8 V absolute maximum and threshold VGS(th) 0.4 to 1.2 V at ID = 250µA.
2 S passive Source; body diode anode side, continuous source current IS up to 3.1 A.
3 D passive Drain; VDS rated 20 V maximum, continuous drain current ID = 3.1 A at TA = 25°C (pulsed IDM 12.4 A).
