BZB84-C3V3-QR

Overview

The Nexperia BZB84-C3V3-QR is a dual voltage regulator diode in a SOT-23 (TO-236AB) surface-mount 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 3.3 V with approximately ±5% tolerance. Key electrical parameters include a total power dissipation of 300 mW, a non-repetitive peak reverse power dissipation of 40 W per diode, and a maximum forward voltage of 0.9 V at 10 mA. It 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 integrating two independent Zener diodes in a single compact SOT-23 package.
• Qualified according to AEC-Q101 standards, making it suitable for demanding automotive electronic applications.
• Offers low differential resistance and tight voltage tolerance options, with the 'C' suffix indicating approximately ±5% accuracy.

Applications

• General regulation functions in dual-channel circuits
• Automotive electronics requiring AEC-Q101 qualified components
• Voltage reference applications utilizing dual common anode topology

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current data sheet to ensure correct packaging and tolerance selection. Confirm that the SOT-23 footprint matches the design layout requirements. Check for any recent product status changes or longevity program updates from Nexperia before finalizing procurement plans.

Selection Notes

Select this component when a dual Zener configuration with a shared anode is required in a small surface-mount form factor. The C-series offers approximately ±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 stable breakdown characteristics.

Part Context

This part belongs to the BZB84-Q series, which encompasses various dual Zener diodes with working voltages ranging from 2.4 V to 75 V. The series is designed for high-density circuit designs, offering multiple tolerance grades (B for ±2%, C for ±5%) and configurations within the standard SOT-23 plastic package.

Replacement Considerations

Direct substitutes within the same family include other BZB84-Cxxx-Q variants with different voltage ratings but identical pinout and package. Cross-family replacements require verification of pin compatibility, power dissipation limits, and AEC-Q101 qualification status.
