WM02N28M

Wayon · MOSFETs · SOT-23

WM02N28M 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; gate-source voltage limited to ±10 V absolute maximum, with VGS(th) of 0.4 V min to 1.2 V max at ID = 250 µA.
2 S passive Source; body diode forward voltage VSD is 1.2 V max at IS = 1 A, VGS = 0 V.
3 D passive Drain; drain-source voltage limited to 20 V, with continuous drain current of 2.8 A at TA = 25°C and 10 A pulsed.
