Single Zener Diodes Procurement Notes

Verify the exact suffix designation when ordering, as the -1/TR suffix indicates tape-and-reel packaging which differs from bulk configurations. Confirm compliance with specific environmental regulations such as RoHS3 and REACH status prior to integration. Ensure the DO-213AA footprint matches the design layout. Cross-reference datasheets for any recent production changes or assembly site notifications to guarantee part consistency.

Single Zener Diodes Selection Notes

Select this component when a 150 V Zener voltage is required in a small surface-mount package. The DO-213AA (MLF) form factor offers space efficiency compared to axial leads. Consider the 500 mW power rating for thermal management needs. The wide operating temperature range supports deployment in harsh environments where standard commercial grade parts may fail.

Single Zener Diodes Part Context

This part belongs to the 1N5276 series of glass surface mount Zener diodes originally developed by Microsemi and now produced by Microchip Technology. The series includes various voltage ratings within the same physical package family. The BUR-1 variant specifically denotes the surface-mount version with specific testing and binning criteria defined in the manufacturer's datasheet.

Single Zener Diodes Replacement Considerations

The 1N5276BUR is listed as a parameter-equivalent substitute. Verify that the replacement maintains the same DO-213AA package dimensions and electrical characteristics, including the 150 V Zener voltage and 500 mW power rating, before implementation.
