Single Zener Diodes Procurement Notes

Verify the specific datasheet version for the 1N4573-1/TR variant, as the -1 suffix denotes a bonded package distinct from standard versions. Confirm that the reel quantity matches your assembly requirements. Ensure the manufacturer documentation explicitly supports the -1 suffix functionality for this specific part number before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a stable 6.4 V reference with low temperature drift is required in a through-hole format. The internal metallurgical bond provides superior mechanical stability compared to non-bonded equivalents. Consider the 500 mW power rating and axial lead configuration for compatibility with existing board layouts and thermal management strategies.

Single Zener Diodes Part Context

This part belongs to the 1N4565 through 1N4584A-1 series of Zero-TC Reference Diodes produced by Microchip Technology. The series offers various operating currents and voltage options, all sharing the common 6.4 V nominal characteristic. The -1 suffix specifically identifies the internal metallurgical bond construction available in JAN, JANTX, and JANTXV military qualifications.
