WSE3088 from Winsok Semicon, in a SOT-89. 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 max, with threshold VGS(th) of 0.5 V min to 1.5 V max at ID=250uA. |
| 2 | D | passive | Drain of the N-channel MOSFET, also connected to the drain tab shown on the package; rated 30 V VDS and 7.0 A continuous at Tc=25℃ (28 A pulsed). |
| 3 | S | passive | Source of the N-channel MOSFET; the body diode runs source to drain, with continuous source current IS of 2 A max. |
