WNM4009-3

WILLSEMI Will Semicon · MOSFETs · SOT-23

WNM4009-3 from WILLSEMI Will Semicon, 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 of the N-channel MOSFET; gate-source voltage is rated ±20 V (VGS), and the gate threshold is 1 V min, 1.9 V typ, 2.5 V max at VDS = VGS, ID = 250 µA.
2 S passive Source of the N-channel MOSFET; body diode forward voltage is 0.8 V typ and 1.2 V max at VGS = 0 V, IS = 1 A.
3 D passive Drain of the N-channel MOSFET; drain-source voltage is rated 110 V, with pulsed drain current IDM up to 7 A and continuous ID of 1.70 A at TA = 25 °C (10 s rating).
