Single Zener Diodes Procurement Notes

Verify the specific suffix designation against official Microchip documentation to confirm exact qualification levels and testing requirements. Ensure compatibility with existing board layouts for the D-5B package. Confirm that the component meets all necessary environmental and radiation hardness standards required for the intended mission profile before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 150 V regulation point is required in a surface-mount configuration. Consider the 5 W power rating and ±5% voltage tolerance during thermal analysis. Verify that the operating environment falls within the specified -65°C to +175°C range. Compare against other JANS series variants if different voltage or tolerance specifications are needed.

Single Zener Diodes Part Context

This part belongs to the JANS series of Zener diodes produced by Microchip Technology. The series is designed for high-reliability applications in defense and space sectors. It shares the same base 1N4986 structure but includes specific processing and screening to meet stringent military standards. The D-5B package is standard for this family's surface-mount offerings.
