WNM3400-3 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; the gate-source voltage is rated at ±10 V maximum (VGS), and RDS(on) is specified at VGS of 2.5 V to 10 V. |
| 2 | S | passive | Source of the N-channel MOSFET; the maximum continuous drain current of 5.2 A (TA=25°C) is referenced to this terminal. |
| 3 | D | passive | Drain of the N-channel MOSFET; the drain-source voltage is rated at 30 V maximum (VDS) with a continuous drain current of 5.2 A at TA=25°C. |
