1N5339E3/TR8

Single Zener Diodes Overview

The Microsemi Corporation 1N5339E3/TR8 is a silicon Zener diode with a nominal voltage of 5.6 V and a tolerance of ±2%. It features a maximum power dissipation of 5 W at 25°C, operating temperatures from -65°C to +150°C, and a dynamic impedance of 1.0 Ω maximum. The device utilizes a T-18 axial leaded plastic package and includes an e3 suffix indicating RoHS compliance.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad range of operating currents and temperatures
• Features flexible axial-lead mounting terminals for versatile integration
• Withstands high surge stresses without damage
• Exhibits minimal changes in voltage versus current as defined by voltage regulation specifications

Single Zener Diodes Applications

• Voltage regulation circuits requiring 5.6 V reference
• Power supply protection against overvoltage conditions
• Clamping applications for transient voltage suppression

Single Zener Diodes Procurement Notes

Verify the component matches the exact part number 1N5339E3/TR8 to ensure correct tolerance and packaging. Confirm that the e3 suffix indicates RoHS compliance and TR suffix indicates tape and reel packaging. Check manufacturer documentation for any specific handling or storage requirements related to the plastic encapsulation.

Single Zener Diodes Selection Notes

Select this component when a precise 5.6 V Zener voltage with tight ±2% tolerance is required. Ensure the application can accommodate the 5 W power rating and provides adequate heat sinking if operating near maximum limits. Verify compatibility with the T-18 axial leaded package dimensions for the PCB layout.

Single Zener Diodes Part Context

This device belongs to the JEDEC registered 1N5333B through 1N5388B series of 5.0 watt Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V. The 1N5339 variant specifically targets the 5.6 V regulation point within this family.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 5.6 V, 5 W Zener diodes in the T-18 package with ±2% tolerance. Verify electrical characteristics such as dynamic impedance and thermal resistance match the original design requirements before substitution.
