1N5343B/TR8

Single Zener Diodes Overview

The Microchip Technology 1N5343B/TR8 is a silicon Zener diode with a nominal voltage of 7.5 V and a power dissipation rating of 5 W. It features a ±5% tolerance, indicated by the 'B' suffix, and operates within a temperature range of -65°C to +150°C. The device utilizes an axial-lead T-18 package and is supplied in tape and reel format per EIA-296 standards.

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 integration

Single Zener Diodes Applications

• Voltage regulation circuits requiring 5 W power handling
• High surge stress environments
• General purpose DC voltage reference applications

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. Confirm RoHS compliance status as standard variants may differ from lead-free versions. Ensure thermal management requirements are met for the specified power dissipation ratings during operation.

Single Zener Diodes Selection Notes

Select this component when a 7.5 V Zener reference with 5 W capability is required. The B suffix ensures a tight ±5% voltage tolerance. Consider the T-18 package dimensions and thermal resistance characteristics for proper heat sinking design in the target application.

Single Zener Diodes Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of silicon 5 Watt Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V. The TR8 suffix indicates the device is packaged in a tape and reel configuration suitable for automated assembly processes.

Single Zener Diodes Replacement Considerations
