CJ2321

Changjing · MOSFETs · SOT-23

CJ2321 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 terminal of the P-channel MOSFET; the gate-source voltage is rated VGS ±12 V.
2 SOURCE passive Source terminal of the MOSFET; the continuous source-drain diode current is rated IS -0.59 A.
3 DRAIN passive Drain terminal of the MOSFET; the drain-source voltage is rated VDS -20 V with continuous drain current ID -2.9 A.

CAD (KiCad official)

  • Symbol: CJ2321
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: cj2321-etched.step / cj2321-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cj2321.step / cj2321.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Changjing datasheet (5 pp, sha256 7ed3aa383758b99f, retrieved 2026-10-09, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
