1N5334E3/TR12

Single Zener Diodes Overview

The Microsemi Corporation 1N5334E3/TR12 is a JEDEC registered silicon 5.0-watt Zener diode with a nominal voltage of 3.6 V and ±5% tolerance. It operates within a temperature range of -65°C to +150°C, featuring a maximum dynamic impedance of 2.5 ohms and a reverse leakage current of 150 µA at 1.0 V. The device utilizes an axial-lead T-18 package and includes RoHS compliance indicated by the e3 suffix.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across broad operating currents and temperatures
• Withstands high surge stresses and offers flexible axial-lead mounting terminals
• Features low thermal resistance design for operation at high DC currents
• Moisture classification Level 1 requiring no dry pack storage

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify the specific part number against official Microsemi documentation to confirm RoHS compliance and tape-and-reel packaging specifications. Ensure that the ordering suffix matches the required moisture classification and screening level. Confirm availability status as distribution channels may vary for discontinued or legacy series components.

Single Zener Diodes Selection Notes

Select this component when a precise 3.6 V reference with tight ±5% tolerance is required. Consider the 5 W power dissipation capability and thermal resistance characteristics for adequate heat sinking. Verify compatibility with existing circuit layouts due to the specific T-18 axial lead dimensions and polarity markings.

Single Zener Diodes Part Context

This device belongs to the 1N5333B through 1N5388B series of 5.0-watt Zener diodes. The series provides a wide selection of voltages from 3.3 V to 200 V with various tolerance options identified by suffix letters. These plastic encapsulated devices are designed for robust performance in demanding environments.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 5 W Zener diodes with 3.6 V nominal voltage and ±5% tolerance. Verify mechanical fitment for the T-18 package and ensure thermal management requirements are met by any substitute component.
