**JUXING** · MOSFETs · SOT-23

JX2300 from JUXING, 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 control input; gate-source voltage is limited to ±10 V, with threshold of 0.45 V min, 0.62 V typ and 1.0 V max at ID=250 uA. |
| 2 | SOURCE | passive | Source terminal of the N-channel MOSFET, normally tied to the low-side or ground return. |
| 3 | DRAIN | passive | Drain terminal of the N-channel MOSFET, rated for 20 V drain-source voltage and 4.5 A continuous drain current. |
