Selection Notes

Select this component when a dual Zener solution with a shared anode is required in a small footprint. The BZB84-B9V1 variant provides precise voltage regulation with tight tolerance. Ensure the application current stays within the specified limits to maintain the rated power dissipation and thermal performance.

Part Context

This part belongs to the BZB84 series of general-purpose dual Zener diodes. The series offers a wide range of nominal voltages from 2.4 V to 75 V in both ±2% and ±5% tolerance options. All variants share the same SOT-23 package and pinout, facilitating design flexibility across different voltage requirements.

Replacement Considerations

Other BZB84 series parts with the same package and dual common anode configuration may serve as alternatives if voltage ratings differ. Single Zener diodes like the BZX84 series require circuit redesign due to different pinouts and configurations.
