1N5334A/TR8

Single Zener Diodes Overview

The Microsemi Corporation 1N5334A/TR8 is a silicon Zener diode with a nominal voltage of 3.6 V and a tolerance of ±10%. It features a maximum power dissipation of 5 W at 25°C, operating within a temperature range of -65°C to +150°C. The device utilizes an axial-lead T-18 package and includes a TR suffix for tape and reel packaging. Electrical characteristics include a test current of 350 mA, a maximum dynamic impedance of 2.5 ohms, and a maximum reverse leakage current of 150 µA at 1.0 V.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals suitable for through-hole applications
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B 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 the specific suffix 'TR8' indicates both the tape and reel packaging format and the standard tin-lead terminal plating configuration. Confirm that the A suffix corresponds to the required ±10% voltage tolerance for your design specifications. Ensure compatibility with existing thermal management solutions given the 5 W power rating.

Single Zener Diodes Selection Notes

Select this component when a 3.6 V reference with moderate precision is required. The T-18 package offers robust mechanical stability compared to smaller surface mount alternatives. Consider the thermal resistance of 25°C/W junction-to-lead for heat sinking requirements. Verify that the lead length meets the specified 3/8 inch (10 mm) requirement for accurate thermal calculations.

Single Zener Diodes Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt silicon Zener diodes. The series covers a wide voltage range from 3.3 V to 200 V. The 1N5334A variant specifically targets low-voltage regulation needs within this high-power family, sharing common mechanical and thermal characteristics with its peers.

Single Zener Diodes Replacement Considerations

Equivalent parts within the same series include 1N5333A and 1N5335A for adjacent voltage levels. Surface mount equivalents are available as SMBJ5334 or SMBG5334. Verify that any substitute maintains the same T-18 package dimensions and electrical tolerances.
