Procurement Notes
Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors. Counterfeit parts are prevalent; unauthorized sources lack traceability and quality assurance. Confirm RoHS compliance status and check for specific suffix designations that may alter packaging or material composition before finalizing procurement.
Selection Notes
Select this component for applications requiring a stable 16 V reference within a compact axial leaded package. Ensure the circuit can handle the 500 mW power dissipation limit without exceeding thermal constraints. Verify that the low leakage current meets system requirements for precision applications.
Part Context
This part belongs to the 1N4678–1N4717 series of 500 mW silicon Zener diodes manufactured by Micro Commercial Components. The series covers a wide voltage range from 1.8 V to 43 V, utilizing a consistent DO-35 hermetically sealed glass package designed for robust performance in various electronic environments.
Replacement Considerations
Cross-reference with other manufacturers' 1N4703 equivalents. Ensure replacement parts match the 16 V nominal voltage, 500 mW power rating, and DO-35 package dimensions. Verify that alternative components meet the same ±5% tolerance and leakage current specifications.
