AZ23C18-7-F from Diodes Incorporated, 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, which has a 16.8 to 19.1V Zener voltage range at IZT = 5.0mA for the AZ23C18. |
| 2 | K2 | passive | Cathode of Zener diode 2, which has a 16.8 to 19.1V Zener voltage range at IZT = 5.0mA for the AZ23C18. |
| 3 | A | passive | Common anode of both Zener diodes. The two diodes are in a common anode configuration, with VZ matched within 5% in one case. |
