JY3400X

Shenzhen JingYang · MOSFETs · SOT-23

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.
