1N5334/TR8

Single Zener Diodes Overview

The Microsemi Corporation 1N5334/TR8 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, housed in a T-18 axial-lead plastic package with a TR tape and reel suffix. It provides voltage regulation at a nominal Zener voltage of 3.6V with a ±5% tolerance. The device operates within a temperature range of -65°C to +150°C and features a maximum dynamic impedance of 2.5 ohms at a test current of 350 mA. Maximum reverse leakage current is specified as 150 µA at 1.0V.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across broad operating current and temperature ranges
• Features flexible axial-lead mounting terminals for through-hole integration
• Withstands high surge stresses and exhibits minimal changes of voltage versus current
• Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020

Single Zener Diodes Applications

• Voltage regulation circuits requiring 3.6V reference
• Power supply protection against overvoltage conditions
• Surge stress handling in electronic systems

Single Zener Diodes Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging rather than cut tape or bulk. Confirm RoHS compliance status by checking for an 'e3' suffix, as standard versions may not be compliant. Ensure the manufacturer designation matches Microsemi Corporation specifications for the 1N5334B part number.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power dissipation rating is required for high-current applications. The T-18 package offers low thermal resistance for effective heat sinking. Verify that the 3.6V Zener voltage aligns with circuit requirements and that the ±5% tolerance meets design precision standards.

Single Zener Diodes Part Context

This component belongs to the 1N5333-5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series covers a wide voltage selection from 3.3V to 200V. These devices are designed for robust performance in demanding environments with low thermal resistance characteristics.

Single Zener Diodes Replacement Considerations

Surface mount equivalents such as SMBJ5333 to SMBJ5388B are available. RoHS compliant versions can be identified by adding the e3 suffix to the base part number.
