DZ23C18_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 | A1 | passive | Anode of Zener diode 1, nominal 18 V (17.10 to 18.90 V at 5.0 mA) with its cathode tied to common pin 3. |
| 2 | A2 | passive | Anode of Zener diode 2, nominal 18 V (17.10 to 18.90 V at 5.0 mA) with its cathode tied to common pin 3. |
| 3 | K | passive | Common cathode of both Zener diodes; total power dissipation is rated 300 mW. |
