1N5338C/TR8

Single Zener Diodes Overview

The Microsemi Corporation 1N5338C/TR8 is a silicon 5.0-watt Zener diode with a nominal voltage of 5.1 volts and a tight tolerance of ±2%. It operates within a temperature range of -65°C to +150°C, features a T-18 axial lead package, and includes a TR suffix indicating tape and reel packaging.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation over a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals for through-hole applications

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify the specific C suffix indicates the required ±2% tolerance level. Confirm the TR suffix matches the intended tape and reel handling requirements. Ensure the component meets the necessary thermal dissipation specifications for the target application environment.

Single Zener Diodes Selection Notes

Select this component when a 5.1-volt reference with tight ±2% accuracy is required. The 5-watt power rating supports high maximum DC currents when adequate heat sinking is provided. Verify that the T-18 axial lead package fits the available board space.

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 to 200 volts. Different suffix letters identify specific voltage tolerances, with the C designation providing tighter control than standard variants.
