BZB84-C33-QR

Overview

The Nexperia BZB84-C33-QR is a dual voltage regulator diode featuring a common anode configuration within a SOT23 surface-mounted plastic package. It provides two independent Zener diodes with a nominal working voltage of 33 V and approximately ±5% tolerance. The device supports a total power dissipation of up to 300 mW per unit, with a non-repetitive peak reverse power dissipation capability of 40 W per diode. Qualified under AEC-Q101 standards, it operates across a junction temperature range of -55 °C to +150 °C.

Feature Summary

• Dual common anode configuration integrating two independent Zener diodes in a single compact SOT23 package.
• Automotive-grade qualification compliant with AEC-Q101 standards for reliability in vehicle applications.
• High surge robustness with a non-repetitive peak reverse power dissipation rating of 40 W per diode.

Applications

• General regulation functions
• Voltage reference circuits
• Over-voltage protection

Procurement Notes

Verify the specific suffix 'QR' against official Nexperia documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the selected component matches the required automotive grade (AEC-Q101) and tolerance series ('C' for approx ±5%) for the intended design implementation.

Selection Notes

Select this part when a dual Zener solution with a shared ground reference is required to save board space. The 'C' suffix indicates approximate ±5% voltage tolerance, suitable for general-purpose regulation where tight precision is not critical. Confirm that the 300 mW total power dissipation limit accommodates the thermal conditions of the target application.

Part Context

This component belongs to the BZB84-Q series, which offers a comprehensive range of dual voltage regulator diodes. The series includes various breakdown voltages from 2.4 V to 75 V and different tolerance options (B for ±2%, C for approx ±5%). All variants share the same SOT23 footprint and automotive qualification profile.

Replacement Considerations

Direct functional substitutes within the same family include BZB84-B33-QR for tighter ±2% tolerance or other BZB84-Q series parts with identical pinout and package constraints.
