JX3400ASS

JUXING · MOSFETs · SOT-23

JX3400ASS 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 G input Gate; controls the channel, with VGSS limited to ±12V and a gate threshold of 0.5V min to 1.5V max at 250µA.
2 S passive Source terminal of the N-channel MOSFET, connected to the body diode anode.
3 D passive Drain; VDSS is rated 30V and continuous drain current ID is 5.8A (pulsed IDP 23A).
