Single Zener Diodes Procurement Notes

Verify that the specific part number suffix matches the required military qualification level. Confirm package orientation markings and cathode band identification on the DO-213AA housing. Ensure storage conditions maintain hermetic integrity prior to assembly.

Single Zener Diodes Selection Notes

Select this component when a 3 V reference is required in a surface-mount form factor with strict reliability mandates. Compare against standard commercial equivalents if military certification is not necessary. Verify thermal derating requirements for high ambient temperatures.

Single Zener Diodes Part Context

This device belongs to the 1N4619 series of Zener diodes, specifically the JANTXV grade which denotes enhanced screening and testing protocols. It serves as a surface-mount alternative to through-hole axial packages while maintaining equivalent electrical performance characteristics for critical applications.

Single Zener Diodes Replacement Considerations

Direct substitutes include other JANTXV graded parts from the same manufacturer family. Cross-reference with other manufacturers' MIL-PRF-19500 qualified devices only if pinout and electrical parameters are identical.
