BZB84-C11-QR

Overview

The Nexperia BZB84-C11-QR is a dual voltage regulator diode in a SOT23 surface-mounted package. It features a common anode configuration with two independent cathodes. The device provides a nominal working voltage of 11 V, falling within the E24 range of 2.4 V to 75 V. It belongs to the C tolerance series, offering approximately ±5% accuracy. Total power dissipation is rated at ≤300 mW per device, with a non-repetitive peak reverse power dissipation of up to 40 W. The component is qualified according to AEC-Q101 standards for automotive applications and operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

• Dual common anode configuration integrating two Zener diodes in a single compact SOT23 package
• Automotive qualification compliant with AEC-Q101 standards for high reliability
• Approximately ±5% voltage tolerance providing flexibility in general regulation designs

Applications

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

Procurement Notes

Verify the specific suffix 'QR' against the manufacturer's current ordering information to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the selected variant matches the required automotive grade and tolerance class for the intended application environment.

Selection Notes

Select this component when a dual Zener solution with a common anode is required in a space-constrained design. The C-series tolerance suits applications where strict voltage precision is not critical. Verify that the 300 mW total power dissipation rating accommodates the thermal conditions of the target PCB layout.

Part Context

This part belongs to the BZB84-Q series, which offers 74 types with nominal voltages from 2.4 V to 75 V. The series includes B (±2%) and C (±5%) tolerance options. All variants share the same SOT23 plastic package and AEC-Q101 automotive qualification, differing primarily in breakdown voltage and marking codes.

Replacement Considerations

Direct substitutes include other BZB84-Q series parts with identical dual common anode configurations. Single Zener equivalents like the BZX84-B11-Q require circuit redesign due to pinout differences. Verify thermal resistance and package compatibility before swapping.
