Single Zener Diodes Procurement Notes

Verify the specific part number suffix against official MCC documentation to confirm packaging configuration, as suffixes indicate variations such as tape-and-reel or bulk quantities. Ensure compliance with RoHS directives and check for any specific handling requirements related to the hermetic glass package during assembly.

Single Zener Diodes Selection Notes

Select this component when a precise 18V reference is required within a through-hole DO-35 form factor. Consider the 500mW power rating and thermal resistance characteristics relative to the operating environment. Verify that the application does not require life support usage without explicit manufacturer approval.

Single Zener Diodes Part Context

This component belongs to the 1N4614 through 1N4125 series of 500mW silicon Zener diodes produced by Micro Commercial Components. The series covers a wide voltage range from 1.8V to 47V, utilizing a consistent DO-35 package and double slug construction methodology across all variants.

Single Zener Diodes Replacement Considerations

Consult official datasheets for equivalent parts from other manufacturers offering identical 18V Zener specifications in the DO-35 package. Verify pinout compatibility and thermal performance metrics before substitution.
