CJ2101 from Changjiang Electronics Tech (CJ), in a SOT-323. 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; gate-source voltage limited to ±8.0 V, threshold VGS(th) -0.45 V min to -0.7 V typ at ID=-250µA. |
| 2 | SOURCE | passive | Source of the P-channel MOSFET; body diode runs source to drain with forward voltage -1.2 V max at IS=-0.3A. |
| 3 | DRAIN | passive | Drain; drain-source voltage rated -20 V, continuous drain current -1.4 A and pulsed -3.0 A. |
