CJ3400A

Changjing · MOSFETs · SOT-23

CJ3400A from Changjing, 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 MOSFET gate terminal; the gate-source voltage is rated at VGS ±12 V maximum.
2 SOURCE passive MOSFET source terminal, the reference for VGS; the device is rated for 5.8 A continuous drain current and 30 A pulsed drain current.
3 DRAIN passive MOSFET drain terminal; the drain-source voltage is rated at VDS 30 V maximum.
