JY3400X from Shenzhen JingYang, 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 | G | input | Gate; gate-source voltage is limited to ±12 V maximum, with a typical threshold VGS(th) of 0.7 to 1.4 V at ID = 250 uA. |
| 2 | S | passive | Source; continuous source (body diode) current is 2.5 A maximum. |
| 3 | D | passive | Drain; drain-source voltage is 30 V maximum, with continuous drain current of 5.8 A at TA=25C and 30 A pulsed. |
