BZB84-B75-QR

Overview

The Nexperia BZB84-B75-QR is a dual voltage regulator diode in the BZB84-Q series, housed in an SOT23 (TO-236AB) surface-mount package. It features a dual common anode configuration with two independent cathodes. The nominal Zener voltage is 75 V with a ±2% tolerance. Key electrical parameters include a maximum total power dissipation of 300 mW, a forward voltage of 0.9 V at 10 mA, and a non-repetitive peak reverse power dissipation of 40 W. The device operates within a junction temperature range of -55 °C to +150 °C and is qualified according to AEC-Q101 standards for automotive applications.

Feature Summary

• Dual common anode configuration providing two independent regulation channels in a compact SOT23 package.
• Qualified according to AEC-Q101 standards, making it suitable for demanding automotive electronic environments.
• Offers tight voltage tolerance options, including the 'B' series with ±2% accuracy for precision reference applications.

Applications

• General voltage regulation functions in electronic circuits.
• Voltage reference applications requiring stable potential levels.
• Automotive electronics systems requiring AEC-Q101 qualified components.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to ensure correct packaging and tape specifications. Confirm that the component status remains active or production-ready before finalizing design-in decisions. Cross-reference the datasheet revision date to ensure all thermal and electrical characteristics align with the latest manufacturing data.

Selection Notes

Select this component when a dual-channel voltage reference or regulation is required in a space-constrained SOT23 footprint. The 75 V rating and ±2% tolerance make it suitable for higher voltage reference needs compared to lower-voltage variants in the same series. Ensure the circuit design accounts for the 300 mW total power dissipation limit and the thermal resistance characteristics under expected operating conditions.

Part Context

This part belongs to the Nexperia BZB84-Q series, which comprises 74 types of dual voltage regulator diodes covering nominal working voltages from 2.4 V to 75 V. The series is designed for general-purpose regulation in small-scale, high-density circuit designs. The 'Q' suffix indicates qualification for automotive applications, distinguishing it from standard commercial grade devices in the broader BZB84 family.

Replacement Considerations

Direct replacements within the same series include other BZB84-Bxx-Q variants with different Zener voltages but identical pinouts and packages. For single-diode applications, the BZX84-B75-QR may serve as a functional alternative if dual configuration is not required, though power dissipation ratings differ slightly.
