Single Zener Diodes Procurement Notes

Verify the specific revision level and lot traceability documentation upon procurement. Confirm that the component meets all applicable military quality assurance requirements. Ensure storage conditions align with the specified moisture sensitivity level to maintain device integrity before assembly.

Single Zener Diodes Selection Notes

Select this component when a 75V regulation point is required in a compact surface-mount form factor. The JANTX grade offers tighter parameter tolerances compared to standard JAN devices. Consider the thermal management capabilities inherent to the DO-213AA package for the specific circuit design.

Single Zener Diodes Part Context

This part belongs to the 1N41xx series of glass-passivated Zener diodes designed for surface-mount applications. The UR-1 suffix indicates an internally metallurgically bonded construction, which enhances mechanical stability and long-term reliability compared to non-bonded variants in the same voltage class.

Single Zener Diodes Replacement Considerations

Direct substitutes include the JAN1N4131UR-1 for standard military qualification or the JANTXV1N4131UR-1 for enhanced testing levels. Verify pinout compatibility and ensure the replacement meets the specific impedance and voltage tolerance requirements of the original design.
