# AZ23C5V1

**Changjing** · Zener Diodes · SOT-23

AZ23C5V1 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 (AZ23C5V1: VZ 4.8-5.4 V at IZT=5.0mA) in the common-anode dual configuration. |
| 2 | K2 | passive | Cathode of zener diode 2 (AZ23C5V1: VZ 4.8-5.4 V at IZT=5.0mA) in the common-anode dual configuration. |
| 3 | A | passive | Common anode of both zener diodes; the datasheet rates 300 mW power dissipation per package. |

## CAD (KiCad official)

- Symbol: `AZ23C5V1`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `az23c5v1-etched.step` / `az23c5v1-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `az23c5v1.step` / `az23c5v1.glb` are the bare package body.
