1N5339AE3/TR8

Single Zener Diodes Overview

The Microsemi Corporation 1N5339AE3/TR8 is a silicon Zener diode with a nominal voltage of 5.6V and a tolerance of ±10%. It features a maximum power dissipation of 5.0 watts at 25°C, operating within a temperature range of -65°C to +150°C. The device utilizes an axial-lead T-18 package and includes a tape and reel option indicated by the TR suffix. It is RoHS compliant due to the e3 suffix.

Single Zener Diodes Feature Summary

• Provides 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 versatile integration

Single Zener Diodes Applications

• Voltage regulation circuits requiring robust thermal performance
• Power supply protection against high surge stresses
• General-purpose voltage reference applications

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'e3' confirms RoHS compliance and 'TR' indicates tape and reel packaging. Confirm the 'A' suffix corresponds to the required ±10% voltage tolerance. Ensure the manufacturer is identified as Microsemi Corporation or its successor entity, as corporate structures may have changed since the document date.

Single Zener Diodes Selection Notes

Select this component when a 5.6V Zener voltage with ±10% tolerance is required. The 5-watt power rating supports high DC currents with adequate heat sinking. The T-18 axial lead package allows for standard through-hole mounting. Verify thermal resistance requirements against the specific application's ambient temperature conditions.

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 voltages from 3.3V to 200V. The 1N5339 designation specifically identifies the 5.6V variant within this family of plastic encapsulated devices designed for high-power regulation.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 5.6V 5W Zener diodes in the T-18 package. Check for suffix compatibility regarding tolerance (A for ±10%) and packaging (TR for tape and reel). Verify RoHS status if environmental compliance is mandatory.
