1N5342E3/TR8

Single Zener Diodes Overview

The Microchip Technology 1N5342E3/TR8 is a silicon 5-watt Zener diode with a nominal voltage of 6.8V and a ±5% tolerance. It operates within a temperature range of -65°C to +150°C, featuring a maximum reverse leakage current of 10µA at 3.0V and a dynamic impedance of 1.0 ohm. The device utilizes an axial-lead T-18 package and includes the TR suffix for tape-and-reel packaging.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Features flexible axial-lead mounting terminals in a void-free transfer molded epoxy body

Single Zener Diodes Applications
