Selection Notes

Select the BZB84-C5V6 variant when a dual Zener solution with common anode topology is required. The C-series provides approximately ±5% voltage tolerance, which is suitable for general-purpose regulation where tight precision is not critical. Ensure the design accounts for the shared thermal environment of the two diodes within the single SOT-23 package.

Part Context

This component belongs to the Nexperia BZB84 series of dual Zener diodes. The series offers various breakdown voltages from 2.4 V to 75 V in both ±2% (B-series) and ±5% (C-series) tolerances. All variants share the same SOT-23 footprint and common anode pinout, allowing for flexible design choices based on voltage requirements while maintaining consistent board space utilization.

Replacement Considerations

Direct functional replacements within the same family include other BZB84-Cxxx parts with different voltage ratings but identical packaging and pinout. Cross-package replacements are not directly compatible without schematic redesign due to the specific dual-diode common anode configuration.
