1N5338/TR8

Single Zener Diodes Overview

The Microsemi Corporation 1N5338/TR8 is a silicon Zener diode with a nominal voltage of 5.1V and a power dissipation rating of 5.0 watts at 25°C. It features an axial-lead T-18 plastic package and operates within a temperature range of -65°C to +150°C. The device provides voltage regulation over broad operating current and temperature ranges, characterized by minimal changes in voltage versus current. It withstands high surge stresses and is non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across wide operating current and temperature ranges
• Withstands high surge stresses while maintaining minimal voltage variation relative to current changes
• Features flexible axial-lead mounting terminals for versatile integration

Single Zener Diodes Applications

• Voltage regulation in electronic circuits
• Protection against high surge stresses
• General-purpose voltage reference applications

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration to confirm tolerance levels and compliance status. Confirm that the TR suffix indicates tape and reel packaging as specified in JEDEC standards. Ensure the component meets required thermal management specifications for the intended application environment.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power rating and 5.1-volt regulation are required. Consider the T-18 package dimensions for board layout constraints. Evaluate thermal resistance requirements based on the specific mounting method and ambient temperature conditions.

Single Zener Diodes Part Context

This part belongs to the JEDEC registered 1N5333 through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V with various tolerance options identified by suffix letters. The manufacturer also provides surface mount equivalents and military screening options within this product family.

Single Zener Diodes Replacement Considerations

Surface mount equivalents such as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B are available. RoHS compliant versions can be identified by adding the e3 suffix to the part number.
