AZ23C13W

Changjing · Zener Diodes · SOT-323

AZ23C13W from Changjing, in a SOT-323. 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 K1 passive Cathode of zener diode 1 (13 V class, VZ 12.4-14.1 V at IZT=5.0 mA); the other end of the diode connects to common pin 3.
2 K2 passive Cathode of zener diode 2 (13 V class, VZ 12.4-14.1 V at IZT=5.0 mA); the other end of the diode connects to common pin 3.
3 A passive Common anode of both zener diodes; power dissipation is 200 mW for the package.

CAD (KiCad official)

  • Symbol: AZ23C13W
  • Footprint: Package_TO_SOT_SMD:SOT-323_SC-70
  • 3D model: SOT-323 (KiCad packages3D, STEP)
  • 3D model files: az23c13w-etched.step / az23c13w-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); az23c13w.step / az23c13w.glb are the bare package body.
