Single Zener Diodes Procurement Notes

Verify the specific suffix configuration to ensure the presence of the internal metallurgical bond required for high-reliability applications. Confirm that the DO-35 through-hole package aligns with the target PCB layout constraints. Cross-reference the manufacturer's datasheet for the latest environmental compliance status and any recent product change notifications affecting material composition or manufacturing location.

Single Zener Diodes Selection Notes

Select this component when a stable 6.4 V reference with tight tolerance is required in harsh thermal environments. The 4 mA test current setting distinguishes it from lower-current variants in the series. Ensure the application can accommodate the specified Zener impedance and leakage characteristics. This part is suitable for designs demanding higher ruggedness than standard glass diodes due to its bonded construction.

Single Zener Diodes Part Context

This device belongs to the 1N4565 through 1N4584A-1 series of Zero-TC Reference Diodes manufactured by Microchip Technology (formerly Microsemi). These components are designed to provide precise voltage references with minimal drift over temperature. The series includes various operating currents and voltage options, with the '-1' suffix denoting the availability of an internal metallurgical bond for improved mechanical strength.

Single Zener Diodes Replacement Considerations

Consult official substitution lists for electrically equivalent parts within the same family. Verify compatibility regarding package dimensions and pinout if replacing with non-suffix variants.
