1N5340B/TR8

Single Zener Diodes Overview

The Microchip Technology 1N5340B/TR8 is a silicon Zener diode with a nominal voltage of 6.0 V and a tolerance of ±5%. It features a maximum power dissipation of 5.0 W at 25°C, a test current of 200 mA, and a maximum dynamic impedance of 1.0 Ω. The device operates within a temperature range of -65°C to +150°C and utilizes a T-18 axial lead package.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals for through-hole integration

Single Zener Diodes Applications

• Voltage regulation circuits requiring 5W power handling
• High current applications with adequate heat sinking
• Surge protection environments

Single Zener Diodes Procurement Notes

Verify the specific suffix 'TR8' against official documentation to confirm tape and reel packaging specifications. Confirm RoHS compliance status as standard B-suffix devices may not be compliant without the e3 designation. Validate manufacturer origin between Microsemi and Microchip Technology due to corporate acquisition history.

Single Zener Diodes Selection Notes

Select this component for applications requiring a 6V reference with ±5% precision. Ensure thermal management design accommodates the 5W dissipation rating. Verify that the T-18 package dimensions fit the target PCB layout constraints.

Single Zener Diodes Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series covers a voltage selection from 3.3V to 200V. The TR8 suffix indicates availability in tape and reel packaging per EIA-296 standards.

Single Zener Diodes Replacement Considerations

Equivalent parts include 1N5340B (standard bulk) and MV1N5340B (military screened). Cross-reference with other manufacturers offering 6V 5W T-18 Zener diodes if supply is restricted.
