CJ2312 from Changjing, 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 | GATE | input | Gate terminal of the N-channel MOSFET, rated for a gate-source voltage of ±8.0 V (VGS) with a gate threshold of 0.45 V to 1.0 V. |
| 2 | SOURCE | passive | Source terminal, the reference for VGS, with a continuous source-drain diode current rating (IS) of 1.04 A. |
| 3 | DRAIN | passive | Drain terminal, rated for a drain-source voltage (VDS) of 20 V, a continuous drain current of 5 A (t=5s) and a pulsed drain current of 20 A. |
