• Computer application voltage regulation

Single Zener Diodes Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm specific ordering suffixes such as PBFREE or TIN/LEAD if required, as these denote plating variations rather than functional changes. Ensure compliance with relevant environmental regulations before integration into final assemblies.

Single Zener Diodes Selection Notes

Select this component when a 100 V Zener voltage with tight 5% tolerance is required in a standard axial package. Consider the 500 mW power rating and wide thermal operating range for suitability in demanding environments. Evaluate alternative manufacturers if availability is constrained due to end-of-life status.

Single Zener Diodes Part Context

This part belongs to the 1N5221B through 1N5278B series of 500 mW silicon Zener diodes. The series offers a broad selection of voltages ranging from 2.4 V to 170 V. All devices share the same DO-35 case outline and general electrical characteristics, differing primarily in their specific breakdown voltage and impedance values.

Single Zener Diodes Replacement Considerations

The datasheet indicates that high voltage 500 mW Zener diodes in the DO-35 package are discontinued and classified as End of Life (EOL). No direct replacement part numbers are provided by the manufacturer for this specific item.
