AZ23C18_R1_00001 from PANJIT International, 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 common-anode dual; the C18 version has a nominal Zener voltage of 18 V (17.10 to 18.90 V) at 5.0 mA. |
| 2 | K2 | passive | Cathode of Zener diode 2 in the common-anode dual; the C18 version has a nominal Zener voltage of 18 V (17.10 to 18.90 V) at 5.0 mA. |
| 3 | A | passive | Common anode of both Zener diodes; total power dissipation is rated 300 mW. |
