BZB84-C68-QR

Overview

The BZB84-C68-QR is a dual voltage regulator diode from the Nexperia BZB84-Q series, housed in an SOT23 surface-mounted package. It features a common anode configuration with two independent cathodes. The device provides a nominal working voltage of 68 V with a tolerance of approximately ±5 %. Key electrical parameters include a total power dissipation of 300 mW and a non-repetitive peak reverse power dissipation of 40 W. The junction temperature range extends up to 150 °C, and it meets AEC-Q101 automotive qualification standards.

Feature Summary

• Dual common anode configuration integrating two Zener diodes in a single compact SOT23 package
• Automotive-grade reliability qualified according to AEC-Q101 standards for harsh environment applications
• High surge capability with non-repetitive peak reverse power dissipation rated at 40 W per diode

Applications

• General voltage regulation functions in automotive electronic circuits
• Overvoltage protection for sensitive input lines
• Voltage reference generation in dual-channel signal conditioning

Procurement Notes

Verify the specific ordering suffix matches the required tolerance grade and voltage rating. Confirm that the component status remains as 'Product data sheet' indicating full production availability. Ensure the sourcing channel provides original manufacturer documentation to validate authenticity against the official Nexperia datasheet specifications.

Selection Notes

Select this variant when a precise 68 V regulation point with ±5 % tolerance is required in a space-constrained design. The dual common anode structure allows for efficient board layout compared to discrete components. Consider the thermal resistance characteristics and PCB footprint requirements during the initial schematic capture phase to ensure adequate heat dissipation.

Part Context

This component belongs to the BZB84-Q series, which offers a wide range of nominal voltages from 2.4 V to 75 V. The series includes both ±2 % (B) and ±5 % (C) tolerance options. All variants share the same SOT23 physical package and pinout, facilitating interchangeable design strategies across different voltage requirements within the same product family.

Replacement Considerations

Direct functional substitutes within the same series include BZB84-B68-Q for tighter tolerance or other BZB84-Q variants for different voltage levels. Cross-brand replacements require verification of pin compatibility, power dissipation limits, and AEC-Q101 qualification status to maintain automotive system integrity.
