JX3400AS3 from JUXING, in a SOT-23-3. 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 | G | input | Gate; the drawing labels it G, with a gate-source rating of ±12 V and a threshold of 0.5 V min to 1.5 V max at 250 µA. |
| 2 | S | passive | Source; the drawing labels it S, and it is the source terminal of the N-channel MOSFET, rated at 7 A continuous drain current. |
| 3 | D | passive | Drain; the drawing labels it D, with a maximum drain-source voltage of 30 V and 7 A continuous (23 A pulsed) drain current. |
