Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required tolerance and packaging configuration. Confirm the specific revision level against the manufacturer's latest datasheet to ensure compatibility with existing designs. Check for any recent Product Change Notifications (PCNs) regarding assembly sites or labeling changes before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed, surface-mount Zener diode with military qualification is required. Ensure the circuit design accommodates the 500 mW power rating and the specific 6.2 V breakdown voltage. Consider the thermal management requirements given the extended temperature range and small form factor of the DO-213AA package.

Single Zener Diodes Part Context

This part belongs to the JAN series of voltage regulator diodes produced by Microchip Technology. These components are engineered for high-reliability applications where standard commercial parts are insufficient. The DUR-1 suffix indicates the specific surface-mount MELF package variant within this broader family of qualified diodes.

Single Zener Diodes Replacement Considerations

Direct substitutes include JAN1N3828A-1C for axial leaded configurations and other JAN1N3828 variants from qualified manufacturers. Verify pinout compatibility and electrical parameter equivalence, particularly the Zener voltage tolerance and power dissipation ratings, before implementing any cross-brand replacements.
