AZ23C16

Changjing · Zener Diodes · SOT-23

AZ23C16 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 K1 passive Cathode of zener diode 1 (AZ23C16: Vz 15.3-17.1V at IZT=5.0mA), in a dual common-anode configuration with 300mW package dissipation.
2 K2 passive Cathode of zener diode 2 (AZ23C16: Vz 15.3-17.1V at IZT=5.0mA), with Vz matched to diode 1 within 5%.
3 A passive Common anode of both zener diodes, shared by pins 1 and 2.

CAD (KiCad official)

  • Symbol: AZ23C16
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: az23c16-etched.step / az23c16-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); az23c16.step / az23c16.glb are the bare package body.
