STK003SF-VB from VBsemi Elec, in a SOT-23(TO-236). 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 terminal of the N-channel MOSFET; the datasheet limits the gate-source voltage to ±20 V. |
| 2 | S | passive | Source terminal of the N-channel MOSFET; the source-drain body diode is rated at 1.4 A continuous at TC = 25 °C. |
| 3 | D | passive | Drain terminal of the N-channel MOSFET; the drain-source voltage is rated at 30 V and the continuous drain current is 6.5 A at TC = 25 °C (package limited). |
