Changjing · MOSFETs · SOT-23
CJK3401 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; gate-source voltage limited to ±12 V, with threshold VGS(th) of -0.7 V min to -1.3 V max at ID=-250µA. |
| 2 | SOURCE | passive | Source of the P-channel MOSFET; continuous drain current is -4.2 A and body diode forward voltage is -1 V max at IS=-1A. |
| 3 | DRAIN | passive | Drain of the P-channel MOSFET; drain-source voltage rated -30 V with RDS(on) of 60 mΩ max at VGS=-10V, ID=-4.2A. |
