1N5339BE3/TR12

Single Zener Diodes Overview

The Microsemi Corporation 1N5339BE3/TR12 is a silicon unidirectional Zener diode with a nominal voltage of 5.6 V and a maximum power dissipation of 5.0 W at 25 °C. 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 a T-18 axial lead plastic package and includes an e3 suffix denoting RoHS compliance. It is supplied in tape and reel packaging 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 versatile installation
• Moisture classification is Level 1, requiring no dry pack storage

Single Zener Diodes Applications

• Voltage regulation circuits
• Surge protection applications
• Reference voltage generation

Single Zener Diodes Procurement Notes

Verify that the component matches the specific JEDEC registered series designation and confirms the presence of the e3 suffix for RoHS compliance. Ensure the tape and reel configuration aligns with automated assembly requirements. Confirm the manufacturer origin as Microsemi Corporation or its authorized successor entity to guarantee authenticity and adherence to the specified electrical characteristics.

Single Zener Diodes Selection Notes

Select this component when a 5.6 V reference with 5 W power handling capability is required. The B suffix indicates a standard 5% tolerance suitable for general regulation tasks. Consider the thermal resistance specifications and derating curves if operating near maximum limits. Verify compatibility with existing PCB layouts due to the specific T-18 axial lead dimensions.

Single Zener Diodes Part Context

This part belongs to the 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. Variations in tolerance are defined by suffix letters, while military screening options exist with specific prefixes. The e3 suffix denotes environmental compliance without altering the functional parameters.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 5.6 V, 5 W Zener diodes in the T-18 package with ±5% tolerance. Verify pinout polarity and thermal characteristics before substitution.
