BZB84-C8V2-QR

Overview

The Nexperia BZB84-C8V2-QR is a dual voltage regulator diode in the BZB84-Q series, housed in an SOT-23 (TO-236AB) surface-mounted plastic 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 8.2 V with approximately ±5% tolerance. Key electrical parameters include a total power dissipation of 300 mW and a non-repetitive peak reverse power dissipation of 40 W per diode. It 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 integrating two Zener diodes in a compact SOT-23 package
• Qualified according to AEC-Q101 for use in automotive electronic applications
• Offers general regulation functions with low forward voltage characteristics

Applications

• General voltage regulation circuits
• Automotive electronics requiring AEC-Q101 qualified components
• Over-voltage protection schemes utilizing dual diode functionality

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to ensure correct packaging and tape-and-reel specifications. Confirm that the component meets all required automotive qualification standards if deployed in safety-critical systems. Cross-reference the marking code UP% on the physical device to validate authenticity and part identity before integration into production lines.

Selection Notes

Select this component when a dual Zener solution with a shared anode is required in a small surface-mount footprint. The C-series designation indicates an approximate ±5% voltage tolerance, suitable for general-purpose regulation where tighter precision is not critical. Ensure the application current remains within the specified limits to maintain the 300 mW total power dissipation rating without exceeding thermal constraints.

Part Context

This part belongs to the Nexperia BZB84-Q series, which comprises 74 types of dual voltage regulator diodes. The series covers nominal working voltages from 2.4 V to 75 V in the E24 range. The BZB84-Q series is specifically designed for surface-mounted design applications, offering normalized tolerance options including ±2% (B-series) and approximately ±5% (C-series) configurations.

Replacement Considerations

Direct substitutes within the same family include other BZB84-Q series variants with identical pinouts but different voltage ratings or tolerances. For equivalent performance, verify that any replacement maintains the SOT-23 package dimensions and AEC-Q101 qualification status to ensure compatibility with existing automotive-grade designs.
