• Over-voltage protection
• General regulation functions

Single Zener Diodes Procurement Notes

Verify the specific suffix 'CC' confirms the dual common cathode configuration rather than a single unit. Ensure the 'HF' designation aligns with RoHS compliance requirements for your assembly process. Confirm the manufacturer is Comchip Technology to avoid counterfeit components. Check datasheet revisions for any updates to thermal or electrical limits before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a dual Zener solution is required in a compact SOT-23 footprint. The 47 V rating suits applications needing precise voltage clamping at this level. Consider the 350 mW power dissipation limit for thermal management. Verify that the 1 kΩ impedance meets the noise and stability requirements of the target application compared to lower impedance alternatives.

Single Zener Diodes Part Context

This part belongs to the BZX84 series of small-signal Zener diodes. It shares the standard SOT-23 form factor with other variants in the family but differs in internal configuration and voltage rating. The dual common cathode setup allows for independent or combined voltage referencing within a single package, optimizing board space compared to using two discrete single diodes.

Single Zener Diodes Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the dual common cathode configuration, 47 V nominal voltage, 5% tolerance, and SOT-23-3 package constraints.
