1N5269BUR-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N5269BUR-1/TR is a surface mount Zener voltage regulator with a nominal breakdown voltage of 87 V and a maximum power dissipation of 0.5 W. It utilizes a hermetically sealed DO-213AA (MELF) package and features a metallurgical bond for enhanced reliability. The device offers a standard tolerance of ±5% and operates within a junction temperature range of -65°C to +175°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass MELF package with internal metallurgical bonding
• Surface mount equivalent to the JEDEC registered 1N5221 through 1N5281 series
• Inherently radiation hard per Microsemi specifications
• Non-sensitive to electrostatic discharge

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• High-reliability electronic circuits requiring radiation hardness
• Applications necessitating minimal capacitance characteristics

Single Zener Diodes Procurement Notes

Verify that the specific part number includes the TR suffix to confirm tape and reel packaging compliance with EIA-481-B standards. Confirm RoHS status, as commercial versions are available in compliant configurations while others may not be. Ensure the ordering suffix matches the required voltage tolerance level for the intended design specifications.

Single Zener Diodes Selection Notes

Select this component when a ruggedized surface mount solution is required for high-voltage regulation up to 200 V. The DO-213AA package provides a direct footprint alternative to axial-leaded equivalents. Consider the positive temperature coefficient inherent to voltages above 5 V when designing for thermal stability across the specified operating range.

Single Zener Diodes Part Context

This device belongs to the 1N5221BUR-1 through 1N5281BUR-1 series of 0.5 W Zener diodes manufactured by Microchip Technology. The series provides a comprehensive selection of breakdown voltages ranging from 2.4 V to 200 V in a standardized surface mount form factor suitable for automated assembly processes.

Single Zener Diodes Replacement Considerations

Equivalent axial-leaded parts include the 1N5269B and 1N5269A. Surface mount alternatives within the same family include the 1N5267BUR-1 and 1N5266BUR-1.
