Single Zener Diodes Procurement Notes

Verify that the specific part number matches the required JANTXV grade specifications for radiation hardness and reliability standards. Confirm package compatibility with PCB footprint requirements prior to ordering. Ensure supply chain sources provide appropriate documentation regarding manufacturing origin and compliance with relevant military specifications.

Single Zener Diodes Selection Notes

Select this component when a low-voltage reference is required in a surface-mount configuration. Consider the thermal derating curve above +50°C when designing for high-power dissipation scenarios. Evaluate the forward voltage drop if the diode is subjected to significant forward bias conditions during operation.

Single Zener Diodes Part Context

This device belongs to the JAN series of voltage regulator diodes produced under MIL-PRF-19500/127 specifications. The JANTXV designation indicates a higher level of screening and quality control compared to standard commercial variants, ensuring suitability for critical applications where failure is not an option.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 2.4 V Zener voltage, 500 mW power rating, and DO-213AA package. Verify that alternative suppliers offer components meeting the same JANTXV reliability standards and temperature operating range.
