Winsok Semicon · MOSFETs · SOT-23-3L
WST4041 from Winsok Semicon, in a SOT-23-3L. 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 P-channel MOSFET, with VGS rated ±20 V absolute maximum and threshold VGS(th) of -0.8 to -2.2 V. |
| 2 | S | passive | Source; main current terminal of the P-channel MOSFET, with continuous drain current of -6.0 A at TC=25℃. |
| 3 | D | passive | Drain; rated for VDS of -40 V, with pulsed drain current of -24 A and RDS(ON) of 30 mΩ typical at VGS=-10V. |
