Single Zener Diodes Procurement Notes

Verify the complete part number including the JAN prefix to ensure military-grade qualification. Confirm the specific suffix indicates the correct packaging format, as variations exist between bulk and tape-and-reel options. Cross-reference the manufacturer datasheet for detailed mechanical drawings and handling instructions relevant to the specific batch code and date code requirements.

Single Zener Diodes Selection Notes

Select this component when a stable 6.4 V reference is required in high-temperature applications. The low temperature coefficient makes it superior to standard Zener diodes for precision analog circuits. Ensure the PCB layout accommodates the DO-35 axial form factor and that the 500 mW power rating aligns with the expected operating current and ambient thermal conditions.

Single Zener Diodes Part Context

This component belongs to the JAN series of Zener diodes produced by Microchip Technology. The JAN designation typically signifies compliance with military quality standards, distinguishing it from commercial variants. It is part of a broader family of temperature-compensated diodes designed for critical applications where voltage stability under thermal stress is paramount.

Single Zener Diodes Replacement Considerations

Direct substitutes include other military-grade 6.4 V temperature-compensated Zener diodes in the DO-35 package. Verify compatibility with equivalent specifications such as the 1N4575A or JAN1N4575A. Ensure any replacement maintains the same temperature coefficient and power dissipation ratings to preserve circuit performance.
