1N5281BE3/TR

Single Zener Diodes Overview

The Microchip Technology 1N5281BE3/TR is a 0.5 W glass axial-lead Zener diode in the DO-35 package, featuring an 110 V nominal breakdown voltage with ±5% tolerance (B suffix). It operates within a -65°C to +175°C temperature range and includes RoHS compliance (e3 suffix) and tape-and-reel packaging (TR suffix).

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range.
• Features hermetically sealed glass axial-lead construction for durability.
• Offers flexible mounting terminals compatible with standard through-hole processes.

Single Zener Diodes Applications

• Voltage reference circuits requiring high stability.
• Overvoltage protection in electronic systems.
• General-purpose voltage regulation tasks.

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'e3' confirms RoHS compliance and 'TR' indicates tape-and-reel packaging. Confirm the specific manufacturer origin, as this part number originates from the Microsemi Scottsdale Division, now part of Microchip Technology. Ensure the component matches the required 110V specification before procurement.

Single Zener Diodes Selection Notes

Select this component when a 110V Zener voltage with tight ±5% tolerance is required. The DO-35 glass package suits applications needing hermetic sealing or robust thermal performance up to 175°C. Consider the TR suffix for automated assembly requirements.

Single Zener Diodes Part Context

This device belongs to the JEDEC registered 1N5221 through 1N5281 series of 0.5 W Zener voltage regulators. The series provides a wide selection of voltages from 2.4 V to 200 V, utilizing standard glass axial-lead packages for general-purpose electronics.

Single Zener Diodes Replacement Considerations

Equivalent parts include 1N5281B and 1N5281B-1. Surface mount equivalents are available in the MLL5281B series using the DO-213AA MELF package.
