BZB84-B62-QR

Overview

The Nexperia BZB84-B62-QR is a dual voltage regulator diode featuring a common anode configuration within a SOT-23 surface-mount package. It provides two independent Zener diodes with a nominal working voltage of 62 V and a ±2% tolerance series designation. The device supports a total power dissipation of up to 300 mW and withstands non-repetitive peak reverse power dissipation of 40 W per diode. Qualified under AEC-Q101 standards, it operates across an ambient temperature range of -55 °C to +150 °C and a junction temperature up to 150 °C.

Feature Summary

• Dual common anode configuration integrating two independent Zener diodes in a single compact SOT-23 package.
• Automotive-grade qualification compliant with AEC-Q101 standards for reliable operation in automotive environments.
• High surge capability with non-repetitive peak reverse power dissipation rated at 40 W per diode.

Applications

• General regulation functions
• Automotive electronic circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to ensure correct packaging and tape-and-reel specifications. Confirm that the component status remains listed as production data sheet rather than preliminary or objective development stages before finalizing procurement plans.

Selection Notes

Select this component when a dual Zener solution with a shared reference node is required to save board space. Ensure the circuit design accounts for the 300 mW total power dissipation limit shared between both diodes. Verify that the 62 V breakdown voltage aligns with the target regulation requirements and that the SOT-23 footprint matches the PCB layout constraints.

Part Context

This part belongs to the BZB84-Q series, which offers a comprehensive range of dual Zener diodes with nominal voltages from 2.4 V to 75 V. The series utilizes the standardized SOT-23 plastic package to facilitate automated surface-mount assembly. The 'B' suffix indicates the ±2% tolerance variant, providing tighter voltage accuracy compared to the standard C series.

Replacement Considerations

Compatible substitutes include other BZB84-B62-Q variants from Nexperia with different packaging options. Single-diode equivalents require two separate components and additional board area. Cross-manufacturer replacements must match the SOT-23 pinout, 62 V breakdown voltage, and thermal characteristics.
