Selection Notes

Select this component when a dual Zener solution with a common anode is required in a small footprint. The C-series offers a standard 5% voltage tolerance. Ensure the application current stays within limits to maintain the specified temperature coefficient and power dissipation ratings.

Part Context

This part belongs to the BZB84 series of general-purpose dual Zener diodes from Nexperia. The series covers a wide working voltage range from 2.4 V to 75 V. The BZB84-C47 variant specifically targets the 47 V nominal point within the E24 preferred number series.

Replacement Considerations

Other BZB84 series variants with different voltage ratings or tolerance codes (e.g., BZB84-B47,215 for ±2%) may be considered if voltage or precision requirements differ. Cross-package replacements require verifying pin compatibility and thermal characteristics.
