Changjing · MOSFETs · SOT-523
CJ1012 from Changjing, in a SOT-523. 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, with a gate-source voltage rating of ±12 V (VGS). |
| 2 | SOURCE | passive | Source terminal of the N-channel MOSFET; the datasheet gives no pin-specific limit, only device ratings of 20 V drain-source voltage and 500 mA continuous drain current. |
| 3 | DRAIN | passive | Drain terminal of the N-channel MOSFET, rated for 20 V drain-source voltage and 500 mA continuous drain current at Ta=25℃. |
