1N5342B/TR8

Single Zener Diodes Overview

The Microchip Technology 1N5342B/TR8 is a silicon Zener diode with a nominal voltage of 6.8V and a power dissipation rating of 5W at 25°C. It features a ±5% tolerance, indicated by the 'B' suffix, and utilizes an axial-lead T-18 package. The device operates within a temperature range of -65°C to +150°C and includes a TR8 tape-and-reel packaging option.

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 for through-hole applications

Single Zener Diodes Applications

• Voltage regulation in electronic circuits
• Surge protection applications
• Reference voltage sources

Single Zener Diodes Procurement Notes

Verify the specific manufacturer origin, as this part number has been associated with both Microsemi and Microchip Technology. Confirm RoHS compliance status, as standard versions may contain lead while e3 variants are compliant. Ensure the TR8 suffix matches the required reel specifications for automated assembly processes.

Single Zener Diodes Selection Notes

Select this component when a 6.8V regulation point is required with a 5W power handling capability. The T-18 package is suitable for through-hole mounting where higher thermal mass is beneficial. Consider the B suffix for precise ±5% tolerance requirements compared to other available tolerances.

Single Zener Diodes Part Context

This component belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V. The 1N5342B specifically addresses the 6.8V segment of this lineup, sharing common mechanical and electrical characteristics with its siblings.

Single Zener Diodes Replacement Considerations

Surface mount equivalents such as SMBJ5342B or SMBG5342B are available. Other voltage ratings within the 1N5333B-1N5388B series can replace units requiring different regulation levels.
