Single Zener Diodes Procurement Notes

Verify the specific datasheet revision and manufacturing lot details upon order confirmation. Ensure that the procurement channel is authorized to handle military-grade components. Confirm compliance with relevant export control regulations if applicable. Check for any specific handling requirements due to the hermetic glass construction during storage and installation.

Single Zener Diodes Selection Notes

Select this component when a stable 360 V reference is required at higher power levels up to 5 W. The wide temperature range makes it suitable for applications where standard commercial parts would fail. Consider the high impedance value when designing circuits sensitive to load regulation changes. Ensure the PCB layout supports the thermal dissipation needs of the 5 W rating.

Single Zener Diodes Part Context

This part belongs to the JEDEC registered JANTX series of Zener diodes, known for their use in critical applications. The 'JANTX' designation indicates a higher level of screening and quality control compared to standard commercial variants. It is part of Microchip's extensive portfolio of radiation-hardened and high-reliability semiconductor devices.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 360 V Zener voltage, 5 W power rating, and hermetic glass package. Verify that alternative parts meet the same MIL-spec or JANTX quality standards. Check for equivalent impedance and leakage current specifications to ensure circuit compatibility.
