Single Zener Diodes Procurement Notes

Verify that the specific part number matches the required voltage tolerance and package style. Confirm RoHS compliance status if applicable, as commercial versions may differ from screened military equivalents. Ensure the ordering suffix aligns with the desired tape and reel packaging configuration for automated assembly processes.

Single Zener Diodes Selection Notes

Select this component when a ruggedized surface mount Zener diode is required for high-reliability environments. The DO-213AA package provides a direct footprint replacement for axial-leaded counterparts while maintaining hermetic sealing. Consider the positive temperature coefficient above 5.6 V for thermal stability requirements in precision reference designs.

Single Zener Diodes Part Context

This device belongs to the 1N5221BUR-1 through 1N5281BUR-1 series, which offers a comprehensive range of Zener voltages from 2.4 V to 200 V in a single surface mount form factor. The series maintains compatibility with traditional through-hole JEDEC standards while providing enhanced mechanical robustness suitable for demanding industrial and aerospace applications.

Single Zener Diodes Replacement Considerations

Direct surface mount replacements include other parts within the 1N5221BUR-1 series family. For axial-leaded equivalents, consult the 1N5221B-1 through 1N5281B-1 listings.
