BZM55C7V5-TR

Single Zener Diodes Overview

The BZM55C7V5-TR is a single Zener diode from the Vishay BZM55 series, housed in a MicroMELF surface-mount package. It features a nominal Zener voltage of 7.5 V with a tolerance range of 7 V to 7.9 V at a test current of 5 mA. The device supports a maximum power dissipation of 500 mW and operates within a junction temperature range of -65 °C to +175 °C. Electrical characteristics include a reverse leakage current of less than 0.1 µA at 2 V, dynamic resistance (ZZ) of less than 7 Ω at 5 mA, and a temperature coefficient between 0.03 %/K and 0.07 %/K.
