• Qualified according to AEC-Q101 for automotive reliability
• High non-repetitive peak reverse power dissipation capability

Applications

• General regulation functions
• Automotive electronic circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the selected variant matches the required voltage tolerance and thermal performance for the intended application environment before finalizing procurement orders.

Selection Notes

Select this component when a dual-diode solution is required within a standard SOT23 footprint to save board space. Ensure the design accounts for the 300 mW total power dissipation limit and verify that the 30 V breakdown voltage aligns with the target regulation requirements. Consider the temperature coefficient and reverse leakage current for precision applications.

Part Context

This part belongs to the Nexperia BZB84-Q series, which offers a comprehensive range of dual voltage regulator diodes. The series includes various nominal working voltages from 2.4 V to 75 V, providing options for customized designs in small-scale, high-density circuit layouts across both Japanese and European selection groups.

Replacement Considerations

Direct substitutes within the same series include BZB84-B27-QR (27 V) and BZB84-B33-QR (33 V), provided the voltage difference is acceptable. Single-channel equivalents like the BZX84-B30-QR may be used if only one diode is needed, though pinout compatibility must be verified.
