Changjing · MOSFETs · SOT-523

CJ4153 from Changjing, in a SOT-523. 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 terminal of the N-channel MOSFET, with ESD protection on the gate and a maximum gate-source voltage rating of ±6 V (VGS).
2 SOURCE passive Source terminal of the N-channel MOSFET, the reference for VGS, in a 20 V (VDS) device rated for 0.915 A continuous drain current (note 1).
3 DRAIN passive Drain terminal of the N-channel MOSFET, with a drain-source voltage rating of 20 V and continuous drain current of 0.915 A (note 1).

CAD (KiCad official)

  • Symbol: CJ4153
  • Footprint: Package_TO_SOT_SMD:SOT-523
  • 3D model: SOT-523, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.8 mm nominal SOT-523 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: cj4153-etched.step / cj4153-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cj4153.step / cj4153.glb are the bare package body.
