Single Zener Diodes Procurement Notes

Verify the specific qualification level (JAN, JANTX, JANTXV, or JANS) required for your application, as these levels dictate the screening and testing standards. Confirm that the DO-213AA package orientation matches your PCB footprint design. Ensure compliance with relevant defense or industrial specifications before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed, low-noise Zener diode is required for harsh environments. The 1% tolerance provides precise voltage control compared to standard commercial grades. Consider the MELF form factor for automated surface-mount assembly processes in space-constrained designs.

Single Zener Diodes Part Context

This part belongs to the 1N4099UR through 1N4135UR series of 500mW metallurgically bonded glass surface mount Zener diodes. These components are specifically engineered to meet the rigorous demands of MIL-PRF-19500/435, offering superior performance over standard commercial equivalents in critical applications.

Single Zener Diodes Replacement Considerations

Direct substitutes include other hermetically sealed Zener diodes from the same manufacturer's MIL-qualified lineup, such as the 1N4105DUR-1E3. Verify that any replacement maintains the identical 11V Zener voltage, 1% tolerance, and DO-213AA package dimensions.
