Changjing · MOSFETs · SOT-23-3L
CJK3407 from Changjing, in a SOT-23-3L. 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 P-channel MOSFET, with gate-source voltage rated VGS ±20 V. |
| 2 | SOURCE | passive | Source terminal of the P-channel MOSFET; the datasheet gives no pin-specific limit for this terminal beyond the device ratings (VDS -30 V). |
| 3 | DRAIN | passive | Drain terminal of the P-channel MOSFET, rated VDS -30 V with continuous drain current ID -4.1 A and pulsed IDM -20 A. |
