Procurement Notes

Verify the specific ordering suffix and marking code against the official datasheet before procurement. Confirm that the component meets the required AEC-Q101 qualification standards for your target application environment. Ensure compatibility with the specified SOT23 footprint dimensions during the design phase.

Selection Notes

Select this component when a dual Zener configuration with high voltage accuracy is required. The B-series offers tighter tolerance compared to the C-series. Consider the thermal resistance and power dissipation limits relative to the expected operating ambient temperature and PCB copper area available for heat spreading.

Part Context

This part belongs to the BZB84-Q series, which provides a comprehensive range of dual voltage regulator diodes. The series covers nominal working voltages from 2.4 V to 75 V in both B (±2%) and C (±5%) tolerance grades. All variants share the same SOT23 plastic package and AEC-Q101 automotive qualification.

Replacement Considerations

Direct replacements within the same family include other BZB84-Q series parts with different voltage ratings or tolerance grades, such as BZB84-C15-Q. Cross-family substitution requires verifying pinout compatibility and ensuring equivalent electrical characteristics match the original design requirements.
