1N5334BE3/TR8

Single Zener Diodes Overview

The Microsemi Corporation 1N5334BE3/TR8 is a silicon Zener diode with a nominal voltage of 3.6 V and a maximum power dissipation of 5 W at 25°C. It features a ±5% tolerance, indicated by the 'B' suffix, and operates within a temperature range of -65°C to +150°C. The device utilizes a T-18 axial leaded package with void-free transfer molded epoxy. Electrical characteristics include a maximum dynamic impedance of 2.5 Ω and a maximum reverse leakage current of 150 µA at 1 V.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Features flexible axial-lead mounting terminals for secure installation
• Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020

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 part number includes the e3 suffix for RoHS compliance and TR8 for tape and reel packaging. Confirm the B suffix indicates the required ±5% voltage tolerance. Check for availability as the component status may be discontinued or subject to long lead times. Ensure the supplier provides original manufacturer documentation to validate authenticity and electrical specifications.

Single Zener Diodes Selection Notes

Select this component when a 3.6 V reference with 5 W power handling is required in an axial package. Consider the thermal resistance of 25°C/W junction-to-lead for heat sinking requirements. Evaluate the maximum regulator current and surge current capabilities against circuit demands. Compare with other series members if different voltage levels are needed.

Single Zener Diodes Part Context

This device belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V. The 1N5334BE3/TR8 specifically targets applications requiring precise voltage clamping with standard tolerance in a robust plastic encapsulated form factor suitable for through-hole mounting.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N5334B without the e3 or TR8 suffixes for non-RoHS or loose bulk options. Surface mount equivalents such as SMBG5334B or SMBJ5334B provide similar electrical performance in different packages. Military screened versions like MQ1N5334BE3 offer enhanced reliability for specific environments.
