CJK3400A

Changjing · MOSFETs · SOT-23-3L

CJK3400A from Changjing, in a SOT-23-3L. 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; gate-source voltage limit is ±12 V, with threshold VGS(th) 0.7 V min, 0.9 V typ, 1.4 V max at ID=250µA.
2 SOURCE passive Source of the N-channel MOSFET, connected to the body diode anode; continuous drain current is 5.8 A and pulsed 30 A.
3 DRAIN passive Drain of the N-channel MOSFET; drain-source voltage rated at 30 V, with RDS(on) max 32 mΩ at VGS=10 V.
