CJ3406

Changjing · MOSFETs · SOT-23

CJ3406 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 Gate of the N-channel MOSFET; the datasheet gives VGS(th) of 1 to 3 V at VDS = VGS and ID = 250 µA and a absolute gate-source voltage rating of ±20 V.
2 SOURCE passive Source of the N-channel MOSFET; the device is rated for a drain-source voltage VDS of 30 V and a continuous drain current ID of 3.6 A.
3 DRAIN passive Drain of the N-channel MOSFET; the device is rated for a pulsed drain current IDM of 15 A and a power dissipation PD of 0.35 W.
