Wayon · MOSFETs · SOT-23
WM02N50M 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 ±12 V maximum and a threshold of 0.45 V min to 1 V max at 250 µA. |
| 2 | S | passive | Source; main current terminal of the N-channel MOSFET, with continuous current IS of 5 A maximum through the body diode. |
| 3 | D | passive | Drain; rated for VDS of 20 V and continuous drain current of 5 A (20 A pulsed) at TA=25°C. |
