BZB84-B5V6-QR

Overview

The Nexperia BZB84-B5V6-QR is a dual voltage regulator diode in the BZB84-Q series, housed in an SOT-23 surface-mount package. It features a dual common anode configuration with two independent cathodes. The nominal Zener voltage is 5.6 V with a ±2% tolerance (B selection). Key electrical parameters include a total power dissipation of 300 mW, a maximum reverse current of 1 μA at IZ=5 mA, and a differential resistance of 40 Ω. The device operates within a junction temperature range of -55 °C to +150 °C and is qualified according to AEC-Q101 for automotive applications.

Feature Summary

• Dual common anode configuration providing two independent regulation channels in a single compact package.
• Qualified according to AEC-Q101 standards, making it suitable for demanding automotive electronic environments.
• High precision voltage regulation with tight ±2% tolerance available in the B selection series.

Applications

• General voltage regulation functions
• Automotive circuit protection and reference design

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 component meets all relevant RoHS directives and environmental compliance requirements for the intended deployment region before finalizing procurement orders.

Selection Notes

Select this component when a dual-channel voltage reference or regulation is required in a space-constrained design. The B selection offers tighter voltage tolerance compared to the C series. Ensure the application current remains within the specified limits to maintain the rated power dissipation and thermal performance characteristics.

Part Context

This part belongs to the BZB84-Q series, which provides a comprehensive range of dual Zener diodes from 2.4 V to 75 V. All variants share the same SOT-23 footprint and AEC-Q101 qualification, allowing for consistent board layout and supply chain management across different voltage requirements in automotive and industrial systems.

Replacement Considerations

Direct functional substitutes within the same series include BZB84-C5V6-QR, which shares the package and configuration but has approximately ±5% voltage tolerance. Other BZB84-Q variants can replace this unit if the specific 5.6 V regulation point is not critical to the circuit design.
