Single Zener Diodes Procurement Notes

Verify that the specific suffix 'CUS' corresponds to the required surface-mount configuration and tape-and-reel packaging format. Confirm that the procurement channel provides valid traceability documentation and Certificate of Conformance (CoC) as mandated by military procurement standards. Ensure compliance with export control regulations associated with defense-grade semiconductor components.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed, surface-mount Zener diode with a 9.1 V breakdown voltage is required for space or military applications. Compare against through-hole variants if board layout constraints allow, noting that the CUS suffix denotes the specific surface-mount package type. Validate thermal management requirements against the datasheet specifications for the chosen footprint.

Single Zener Diodes Part Context

This part belongs to the 1N446x series of Zener diodes produced under the JAN/JANTXV quality levels. These devices are characterized by their voidless hermetic sealing and metallurgical bonds, ensuring long-term stability in extreme environments. The series covers a range of voltage ratings from approximately 3.3 V to higher values, all sharing similar robust construction methods.

Single Zener Diodes Replacement Considerations

Direct replacements include other JANTXV qualified parts within the same voltage class, such as JANTXV1N4464D for through-hole applications. Verify pinout compatibility and package dimensions before substituting with commercial grade equivalents, as hermeticity and radiation hardness may differ.
