CJ3134KW

Changjing · MOSFETs · SOT-323

CJ3134KW from Changjing, in a SOT-323. 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 datasheet gives a typical gate-source voltage VGS of ±12 V.
2 SOURCE passive MOSFET source terminal; the datasheet states no pin-specific limit, only device ratings of 20 V VDSS and 0.75 A continuous drain current.
3 DRAIN passive MOSFET drain terminal; the device is rated 20 V drain-source voltage (VDSS), 0.75 A continuous drain current and 3 A pulsed drain current.
