PDZ18BGWX

Single Zener Diodes Overview

The PDZ18BGWX is a single Zener diode from the Nexperia PDZ-GW series, designed for general-purpose regulation functions. It is housed in a SOD-123 surface-mount package with dimensions of 2.8 mm length, 1.6 mm width, and 1.3 mm height. The device features an 18 V nominal Zener voltage with a tight tolerance of ±2%. It supports a total power dissipation of up to 625 mW and operates within a temperature range of -55°C to +150°C. Key electrical characteristics include a maximum reverse leakage current of 5 µA at 14.4 V and a Zener impedance of 15 Ohms at a test current of 5 mA.
