AZ23C4V7-G3-08 from Vishay Intertech, 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 the first Zener diode (VZ 4.4 to 5 V, nominal 4.7 V at IZT 5 mA for AZ23C4V7); the other diode is on pin 2 and both share the common anode on pin 3. |
| 2 | K2 | passive | Cathode of the second Zener diode (VZ 4.4 to 5 V, nominal 4.7 V at IZT 5 mA for AZ23C4V7), with its anode tied to the common anode on pin 3. |
| 3 | A | passive | Common anode of both Zener diodes, shared by pins 1 and 2. |
