1N5268BE3/TR

Single Zener Diodes Overview

The Microchip Technology 1N5268BE3/TR is a 0.5 W glass axial-lead Zener diode in the DO-35 package, featuring an 82 V nominal breakdown voltage with ±5% tolerance (B suffix). It operates within a -65°C to +175°C 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 leads for flexible mounting.
• Offers minimal capacitance characteristics suitable for high-frequency applications.

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels.
• Overvoltage protection stages in power supply designs.
• Clamping applications for transient voltage suppression.

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'e3' confirms RoHS compliance and 'TR' indicates tape-and-reel packaging. Confirm the B suffix denotes the required ±5% voltage tolerance. Ensure the manufacturer designation aligns with Microchip Technology or authorized Microsemi Scottsdale Division sources.

Single Zener Diodes Selection Notes

Select this component when a 0.5 W power rating and axial-lead form factor are required. The 82 V breakdown voltage suits specific mid-range regulation needs. Verify thermal derating requirements against the maximum junction-to-ambient resistance specifications provided in the datasheet.

Single Zener Diodes Part Context

This device belongs to the 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators. The series provides a wide selection from 2.4 to 200 volts with various tolerance options. These components utilize a standard JEDEC registered DO-35 glass body package.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available as MLL5268B in the DO-213AA MELF style package. Direct pin-for-pin replacement requires maintaining the axial lead configuration unless a PCB redesign accommodates the MELF footprint.
