1N5272BUR-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N5272BUR-1/TR is a single silicon Zener diode designed for surface-mount applications. It features a nominal Zener voltage of 110V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 500mW and operates within a unidirectional configuration. It utilizes the DO-213AA (SMB) package, which is a glass-encapsulated, hermetically sealed form factor suitable for automated assembly processes.

Single Zener Diodes Feature Summary

• Hermetically sealed glass encapsulation for environmental protection
• Surface-mount compatible DO-213AA package design
• Single unidirectional Zener voltage regulation capability

Single Zener Diodes Applications

• Voltage reference circuits requiring stable 110V levels
• Overvoltage protection in surface-mount assemblies
• Clamping applications in electronic control modules

Single Zener Diodes Procurement Notes

Verify that the specific part number includes the -1 suffix to confirm the ±5% tolerance variant. Ensure the /TR designation is present to confirm tape-and-reel packaging for automated handling. Cross-reference the manufacturer code to distinguish between Microsemi legacy stock and current Microchip Technology production runs, as both entities have historically produced this component family.

Single Zener Diodes Selection Notes

Select this component when a precise 110V regulation point is required in a compact surface-mount footprint. The DO-213AA package offers higher power density than axial leads while maintaining hermetic sealing. Consider the 500mW power rating against expected thermal conditions in the final assembly to ensure reliable operation under continuous load.

Single Zener Diodes Part Context

This component belongs to the standard Zener diode series manufactured by Microchip Technology. It serves as a surface-mount alternative to traditional axial-leaded versions, providing equivalent electrical characteristics in a smaller form factor. The DO-213AA package is widely recognized in industrial electronics for its robustness and compatibility with standard SMT reflow processes.

Single Zener Diodes Replacement Considerations

Direct substitutes include the 1N5272BUR/TR variant, which shares identical electrical specifications but may differ in packaging quantity or lead-free status. Verify package dimensions and pinout compatibility before substituting any other 110V Zener diodes from different manufacturers.
