BZB84-B10-QR

Overview

The Nexperia BZB84-B10-QR is a dual voltage regulator diode in the BZB84-Q series, housed in an SOT23 surface-mounted plastic package. It features a dual common anode configuration with two independent cathodes (K1, K2) and a shared anode (CA). The device provides a nominal Zener voltage of 10 V with a tolerance of ±2%. Key electrical parameters include a maximum total power dissipation of 300 mW, a non-repetitive peak reverse power dissipation of 40 W per diode, and a 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 standards.

Feature Summary

• Dual common anode configuration for compact circuit design
• AEC-Q101 qualified for automotive applications
• High non-repetitive peak reverse power dissipation capability

Applications

• General regulation functions
• Automotive electronic circuits

Procurement Notes

Verify the specific suffix 'QR' against the manufacturer's current documentation to confirm packaging details such as reel size or tape specifications. Ensure that the ordering code matches the exact voltage tolerance series required for the design, as the BZB84-Q series includes both B (±2%) and C (±5%) variants. Confirm availability through authorized distributors as supply status may vary.

Selection Notes

Select this component when a dual Zener diode with a common anode is required in a small SOT23 package. The B-series designation indicates a tighter ±2% voltage tolerance compared to the C-series. Consider the 300 mW total power dissipation limit and the thermal resistance characteristics when designing for high ambient temperatures or dense PCB layouts.

Part Context

This part belongs to the Nexperia BZB84-Q series of dual voltage regulator diodes. The series offers a wide range of nominal working voltages from 2.4 V to 75 V in the E24 range. All devices in this series share the same SOT23 package and dual common anode topology, differing primarily in their Zener voltage and tolerance grade.

Replacement Considerations

Direct substitutes within the same family include other BZB84-Bxxx-Q parts with different voltage ratings but identical package and tolerance. Cross-brand replacements must match the SOT23-3 footprint, dual common anode configuration, and 10 V Zener voltage specification.
