SK2312AA from Shikues, 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 ±10 V, a threshold of 0.45 to 1.0 V at 250 µA, and ±2700 V ESD protection. |
| 2 | S | passive | Source; the body-diode continuous current is rated 6.8 A and the drain-source voltage rating is 20 V. |
| 3 | D | passive | Drain; rated for VDS 20 V, ID 6.8 A continuous at TA=25°C and 17 A pulsed. |
