1N5272BUR

Single Zener Diodes Overview

The Microchip Technology 1N5272BUR is a single silicon Zener diode designed for surface-mount applications. It features a nominal Zener voltage of 110V with a tolerance of ±5% and a power dissipation rating of 0.5W (500mW). The component utilizes a DO-213AA (MLL34/MELF-2) glass encapsulation package, providing an isolated case connection. It is classified as non-RoHS compliant and contains lead. The device operates as a unidirectional voltage regulator within the specified thermal and electrical limits.

Single Zener Diodes Feature Summary

• Hermetically sealed glass MELF-style construction for environmental protection
• Single unidirectional Zener configuration for voltage regulation
• Surface-mount DO-213AA package design

Single Zener Diodes Applications

• Voltage regulation in electronic circuits
• Overvoltage protection interfaces
• Reference voltage generation

Single Zener Diodes Procurement Notes

Verify compliance status carefully, as this specific part number is documented as non-RoHS compliant and lead-containing. Confirm the exact suffix requirements for your assembly process, as variants such as -1 or -1/TR may exist with different packaging or regulatory attributes. Ensure the supplier provides official datasheets confirming the 110V specification and DO-213AA package type to avoid substitution errors with similar series components.

Single Zener Diodes Selection Notes

Select this component when a 110V Zener voltage is required in a compact surface-mount form factor. The DO-213AA package is suitable for automated placement. Consider the non-RoHS status if the final product requires environmental compliance. Compare against other 1N52xx series variants if different voltage levels are needed, ensuring the 0.5W power rating meets the circuit's dissipation requirements.

Single Zener Diodes Part Context

This device belongs to the Microchip (formerly Microsemi) 1N5272 series of single Zener diodes. It shares the same physical DO-213AA package and general characteristics as related parts like the MX1N5272BUR-1, differing primarily in specific ordering suffixes that may indicate packaging variations or regulatory compliance updates. It is distinct from higher-voltage or lower-power variants within the broader Zener diode family.

Single Zener Diodes Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Variants such as 1N5272BUR-1 or 1N5272BUR-1/TR may be functionally equivalent but require verification of suffix-specific differences regarding RoHS compliance and packaging before substitution.
