1N5338BE3/TR8

Single Zener Diodes Overview

The Microsemi Corporation 1N5338BE3/TR8 is a silicon unidirectional Zener diode with a nominal voltage of 5.1 V and a maximum power dissipation of 5 W. 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 and includes an 'e3' suffix for RoHS compliance and a 'TR' suffix for tape and reel packaging.

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 versatile installation
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B without requiring dry pack

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 against official Microsemi documentation to confirm the specific suffixes for tolerance (B), compliance (e3), and packaging (TR). Ensure that the required thermal management aligns with the specified derating curves for the intended application environment. Confirm availability status as this series may have discontinuation notices.

Single Zener Diodes Selection Notes

Select this component when a 5.1 V Zener voltage with ±5% tolerance is required for 5 W applications. Consider the T-18 axial package for through-hole mounting. Evaluate thermal resistance requirements based on the junction-to-lead and junction-to-ambient specifications provided in the datasheet for proper heat sinking design.

Single Zener Diodes Part Context

This component belongs to the JEDEC registered 1N5333-5388B series of 5.0 watt Zener diodes manufactured by Microsemi. The series offers a wide selection of voltages from 3.3 V to 200 V. The 'e3' designation indicates RoHS compliance, while the 'TR' suffix specifies tape and reel packaging for automated assembly processes.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B. Verify pinout compatibility and thermal performance when substituting with these surface mount devices.
