1N5339E3/TR12

Single Zener Diodes Overview

The Microsemi Corporation 1N5339E3/TR12 is a silicon Zener diode with a nominal voltage of 5.6V and a power dissipation rating of 5.0 watts at 25°C. It features a T-18 axial leaded plastic package and operates within a temperature range of -65°C to +150°C. The device has a maximum dynamic impedance of 1.0 ohm, a test current of 220 mA, and a maximum reverse current of 1.0 µA. The 'e3' suffix indicates RoHS compliance, while the 'TR12' suffix denotes tape and reel packaging.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses due to low thermal resistance design
• Features flexible axial-lead mounting terminals for through-hole applications
• Moisture classification Level 1 requiring no dry pack

Single Zener Diodes Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage sources in measurement equipment

Single Zener Diodes Procurement Notes

Verify that the specific part number matches the required tolerance and packaging configuration. Confirm RoHS compliance status if restricted materials are prohibited in your assembly process. Ensure adequate heat sinking is available during installation to maintain performance within the specified thermal limits.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power rating and 5.6-volt regulation point are required. Consider the T-18 package dimensions for board layout constraints. Evaluate thermal management requirements based on the junction-to-ambient resistance specifications provided in the datasheet.

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 to 200 volts with various tolerance options identified by suffix letters. The e3 suffix specifically denotes RoHS compliant devices within this family.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 5.6V 5W Zener diodes in the T-18 package. Verify electrical characteristics such as dynamic impedance and power derating curves before substitution.
