AZ23C4V3 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 in the dual common-anode pair (VZ 4.0-4.6 V at IZT=5.0mA for AZ23C4V3). |
| 2 | K2 | passive | Cathode of zener diode 2 in the dual common-anode pair (VZ 4.0-4.6 V at IZT=5.0mA for AZ23C4V3). |
| 3 | A | passive | Common anode of both zener diodes, shared by pins 1 and 2. |
