Single Zener Diodes Procurement Notes

Verify that the part number includes the specific suffix indicating MIL-PRF-19500 qualification. Confirm the package type matches the required surface mount footprint. Ensure the manufacturer source is authorized to prevent counterfeit components. Check for RoHS compliance status if required by the end application. Validate the lot traceability documentation upon receipt.

Single Zener Diodes Selection Notes

Select this component when a 22 V regulation point is required in a compact surface mount form factor. The wide temperature range supports operation in extreme environments. The internal metallurgical bond offers superior mechanical stability compared to standard commercial equivalents. Consider the 500 mW power rating for thermal management in dense PCB layouts.

Single Zener Diodes Part Context

This component belongs to the series of 0.5 watt glass surface mount Zener diodes. It serves as the surface mount equivalent of the JEDEC registered axial-leaded 1N4115 series. The design integrates high-reliability screening options suitable for demanding operational conditions.

Single Zener Diodes Replacement Considerations

Direct substitutes include other qualified versions of the 1N4115 series such as JAN1N4115UR-1 or commercial variants like 1N4115UR, provided the electrical parameters and package dimensions are compatible.
