DZ23C18_R1_00001

PANJIT International · Zener Diodes · SOT-23

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.
