• Automotive grade qualification compliant with AEC-Q101 standards
• High precision voltage regulation with narrow tolerance options

Applications

• General regulation functions
• Voltage reference circuits
• Over-voltage protection

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm packaging details and manufacturing origin. Ensure compatibility with standard SOT-23 footprints during PCB layout. Confirm that the selected component meets all required automotive or industrial reliability standards before final integration into the design.

Selection Notes

Select this component when a dual Zener solution with a shared ground reference is required to save board space. The B-series offers tighter voltage tolerances compared to the C-series. Consider the thermal resistance characteristics and ensure adequate heat dissipation if operating near the maximum power dissipation limits under continuous load conditions.

Part Context

This device belongs to the BZB84 series of dual Zener diodes manufactured by Nexperia. The series provides various voltage options ranging from 2.4 V to 75 V in standardized E24 values. These components are designed for general-purpose voltage regulation and protection applications in small-scale, high-density electronic designs requiring reliable performance.

Replacement Considerations

Direct substitutes within the same series include other BZB84 variants with different voltage ratings but identical pinouts. Cross-reference with other manufacturers' dual common-anode Zener diodes in SOT-23 packages, ensuring matching voltage, tolerance, and power dissipation specifications.
