Changjing · MOSFETs · SOT-23
CJ2310 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; gate-source voltage is rated ±20 V, and the device is specified for operation with gate voltage as low as 2.5 V. |
| 2 | SOURCE | passive | Source terminal of the MOSFET; the datasheet gives a diode forward voltage VSD of 1.2 V at IS = 3 A with VGS = 0 V. |
| 3 | DRAIN | passive | Drain terminal of the MOSFET; rated for a drain-source voltage of 60 V and continuous drain current of 3 A (pulsed 10 A). |
