CJ3415 R15 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 of the P-channel MOSFET; the datasheet limits gate-source voltage VGS to ±8 V. |
| 2 | SOURCE | passive | Source of the P-channel MOSFET; the datasheet gives no separate pin-level limit for this terminal. |
| 3 | DRAIN | passive | Drain of the P-channel MOSFET; the datasheet rates drain-source voltage VDS at -20 V. |
