1N5376B/TR8

Overview

The Microsemi Corporation 1N5376B/TR8 is a silicon 5.0-watt Zener diode with an 87 V nominal voltage and ±5% tolerance. It operates in the -65°C to +150°C range, features a T-18 axial lead package, and includes a TR suffix for tape and reel packaging.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal changes of voltage versus current
• Features flexible axial-lead mounting terminals and void-free transfer molded epoxy body

Applications

• Voltage regulation circuits requiring 5W power dissipation
• High surge stress environments
• Applications needing wide selection from 3.3V to 200V

Procurement Notes

Verify the part number against official Microsemi documentation to confirm JEDEC registration and specific suffix requirements. Ensure compatibility with MIL-PRF-19500 screening levels if military equivalents are required. Confirm RoHS compliance status based on the e3 suffix availability.

Selection Notes

Select this component for applications requiring 87V regulation at 5W. Consider thermal resistance and heat sinking needs for maximum DC currents. Verify moisture classification Level 1 requirements and ensure adequate copper pad dimensions for FR4 PC board mounting.

Part Context

Part of the 1N5333-5388B series offering 3.3V to 200V options. Available in various military screening levels (JAN, JANTX, JANTXV) via prefix identifiers. Surface mount equivalents exist as SMBJ or SMBG series.

Replacement Considerations

Check for direct substitutes within the 1N5333-5388B series. Consider SMBJ5376B or SMBG5376B for surface mount alternatives. Verify equivalent electrical characteristics before substitution.
