CJK3401

Changjing · MOSFETs · SOT-23

CJK3401 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 P-channel MOSFET; gate-source voltage limited to ±12 V, with threshold VGS(th) of -0.7 V min to -1.3 V max at ID=-250µA.
2 SOURCE passive Source of the P-channel MOSFET; continuous drain current is -4.2 A and body diode forward voltage is -1 V max at IS=-1A.
3 DRAIN passive Drain of the P-channel MOSFET; drain-source voltage rated -30 V with RDS(on) of 60 mΩ max at VGS=-10V, ID=-4.2A.

CAD (KiCad official)

  • Symbol: CJK3401
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: cjk3401-etched.step / cjk3401-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cjk3401.step / cjk3401.glb are the bare package body.
