BZT55B15-GS18

Single Zener Diodes Overview

The BZT55B15-GS18 is a single silicon Zener diode from the Vishay BZT55 series, designed for surface-mount applications in QuadroMELF (SOD-80) packages. It provides a nominal Zener voltage of 15 V with a tight tolerance of ±2%. The device operates at a test current of 5 mA and supports a maximum power dissipation of 500 mW. Key electrical parameters include a reverse leakage current of less than 0.1 µA at 1 V, a dynamic resistance of less than 30 Ω at the test current, and a temperature coefficient ranging from 0.03 %/K at 25 °C to 0.11 %/K at 150 °C.
