Selection Notes

Select this part when a dual Zener solution with a shared anode is required in a space-constrained design. The BZB84-C51,215 offers a 51 V nominal voltage with 5% tolerance. Ensure the circuit design accounts for the 300 mW total power dissipation limit and the thermal resistance characteristics defined in the datasheet to maintain safe junction temperatures during operation.

Part Context

This component belongs to the BZB84 series, which comprises 74 types covering nominal voltages from 2.4 V to 75 V. The series utilizes the SOT-23 package and is available in two tolerance grades: B (±2%) and C (±5%). The BZB84-C51,215 specifically represents the 51 V variant within the C-tolerance group, providing a standardized option for mid-range voltage regulation needs.

Replacement Considerations

Direct replacements must match the BZB84 series specifications, including the SOT-23 package, dual common anode configuration, and 51 V nominal voltage. Verify that any substitute component meets the same AEC-Q101 qualification status and thermal characteristics if used in automotive contexts.
