BZB84-B33-QR

Overview

The Nexperia BZB84-B33-QR is a dual voltage regulator diode in a SOT23 surface-mounted package. It features a nominal working voltage of 33 V with a ±2 % tolerance series (B). The device has a total power dissipation of 300 mW and a non-repetitive peak reverse power dissipation of 40 W per diode. Operating temperatures range from -55 °C to +150 °C. Key electrical parameters include a maximum forward voltage of 0.9 V at 10 mA, a reverse current of 80 μA at 2 mA test current, and a differential resistance of 0.05 Ω. It is qualified according to AEC-Q101 for automotive applications.

Feature Summary

• Dual common anode configuration within a compact SOT23 plastic package
• Automotive qualification compliant with AEC-Q101 standards
• High precision voltage regulation with ±2 % tolerance series

Applications

• General regulation functions
• Voltage reference circuits
• Over-voltage protection in automotive environments

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the component meets all required environmental and reliability standards for the intended application before finalizing procurement orders.

Selection Notes

Select this component when a dual Zener configuration with a common anode is required in a small footprint. The B-series offers tighter voltage tolerance compared to the C-series. Ensure the operating current stays within limits to maintain the specified temperature coefficient and reverse leakage characteristics.

Part Context

This part belongs to the Nexperia BZB84-Q series, which provides a comprehensive range of dual voltage regulator diodes. The series covers nominal voltages from 2.4 V to 75 V in both ±2 % and ±5 % tolerance options, all housed in the standard SOT23 package suitable for high-density surface-mount designs.

Replacement Considerations

Direct replacements within the same family include other BZB84-Q variants with different voltage ratings but identical pinouts and packages. Verify that any substitute maintains the required AEC-Q101 qualification and thermal characteristics if used in automotive contexts.
