1N5339/TR12

Single Zener Diodes Overview

The Microsemi Corporation 1N5339/TR12 is a silicon Zener diode with a nominal voltage of 5.6V and a tolerance of ±5%. It features a 5W power dissipation rating, operates within a temperature range of -65°C to +150°C, and utilizes an axial-lead T-18 plastic package.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across broad operating current and temperature ranges
• Withstands high surge stresses while maintaining minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals for versatile installation

Single Zener Diodes Applications

• Voltage regulation circuits requiring robust thermal performance
• Power supply protection against high surge stresses
• General-purpose electronic equipment utilizing standard axial lead mounting

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration to confirm compliance requirements and packaging format. The TR suffix indicates tape and reel packaging per EIA-296 standards. Ensure that the selected variant matches the required voltage tolerance and screening level for your application specifications.

Single Zener Diodes Selection Notes

Select this component when a 5.6V reference is needed with a 5W power handling capability. Consider the low thermal resistance design if operating at high maximum DC currents. Verify that the ambient or lead temperatures remain within the specified operational limits during steady-state conditions.

Single Zener Diodes Part Context

This device belongs to the JEDEC registered 1N5333 through 1N5388B series of 5.0-watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V with various tolerance options identified by specific suffix letters on the part number.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 5.6V 5W Zener diodes in the T-18 package. Cross-reference with the broader 1N5333-5388B series for alternative voltage ratings or tighter tolerance variants such as C or D suffixes.
