BZB84-C3V0-QR

Overview

The Nexperia BZB84-C3V0-QR is a dual voltage regulator diode in the BZB84-Q series, housed in an SOT23 surface-mounted package. It features a dual common anode configuration with two independent Zener diodes sharing a single anode terminal. The device provides a nominal working voltage of 3.0 V with a tolerance of approximately ±5%. Key electrical characteristics include a total power dissipation of 300 mW and a non-repetitive peak reverse power dissipation of 40 W per diode. The component is qualified according to AEC-Q101 standards for automotive applications.

Feature Summary

• Dual common anode configuration integrating two Zener diodes in a compact SOT23 package
• AEC-Q101 qualification ensuring suitability for demanding automotive electronic environments
• Approximately ±5% voltage tolerance providing standardized regulation within the E24 range

Applications

• General voltage regulation functions in automotive circuits
• Voltage reference applications requiring dual independent regulation channels
• Over-voltage protection stages in high-density surface-mounted designs

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to ensure compatibility with required packaging formats. Confirm that the AEC-Q101 qualification status meets the specific reliability requirements of the target automotive application before finalizing procurement specifications.

Selection Notes

Select this component when a dual-channel voltage reference or regulation solution is required in a minimal footprint. The C-series designation indicates an approximate ±5% tolerance, which is suitable for general-purpose applications where tighter precision is not critical. Ensure the operating current remains within the specified limits to maintain stable breakdown voltage characteristics.

Part Context

This part belongs to the Nexperia BZB84-Q series, which offers a comprehensive range of dual Zener diodes in the SOT23 package. The series spans nominal voltages from 2.4 V to 75 V, providing designers with flexible options for various regulation needs while maintaining consistent physical dimensions and automotive-grade reliability across the entire product line.

Replacement Considerations

Direct replacements must match the SOT23 package, dual common anode configuration, and 3.0 V nominal voltage. Verify that alternative components meet the same AEC-Q101 qualification and thermal resistance specifications to ensure equivalent performance in automotive environments.
