1N5334AE3/TR12

Single Zener Diodes Overview

The Microsemi Corporation 1N5334AE3/TR12 is a JEDEC registered silicon 5.0-watt Zener diode in the axial-leaded T-18 package. It provides voltage regulation at a nominal Zener voltage of 3.6 volts with a ±10% tolerance, indicated by the 'A' suffix. The device operates within a temperature range of -65°C to +150°C and features RoHS compliance via the 'e3' suffix. Electrical characteristics include a maximum dynamic impedance of 2.5 ohms and a maximum reverse current of 150 µA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across broad operating currents and temperature ranges
• Withstands high surge stresses and offers flexible axial-lead mounting terminals
• Features minimal changes in voltage versus current as specified by voltage regulation parameters

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify that the part number includes the 'e3' suffix for lead-free RoHS compliance and the 'TR12' suffix for tape and reel packaging. Confirm the 'A' suffix indicates the required ±10% voltage tolerance. Ensure the component meets the specific moisture classification Level 1 requirements without dry pack constraints.

Single Zener Diodes Selection Notes

Select this component when a 3.6-volt regulation point with ±10% tolerance is required in a 5-watt power dissipation class. The T-18 through-hole package is suitable for applications needing adequate heat sinking to handle high maximum DC currents. Verify compatibility with standard FR4 printed circuit board layouts for optimal thermal resistance.

Single Zener Diodes Part Context

This device belongs to the 1N5333B through 1N5388B series of JEDEC registered axial-leaded Zener diodes. The series covers a wide selection from 3.3 to 200 volts with various tolerance options identified by specific suffix letters. These plastic encapsulated devices are designed for high reliability and offer surface mount equivalents in SMBJ and SMBG packages.

Single Zener Diodes Replacement Considerations

Equivalent parts within the same series include 1N5334B or 1N5334Be3 for identical electrical specifications. Surface mount replacements are available as SMBJ5334A or SMBJ5334Be3.
