BZB84-C6V2-QR

Overview

The Nexperia BZB84-C6V2-QR is a dual voltage regulator diode in a SOT-23 (TO-236AB) surface-mount package. It features a nominal Zener voltage of 6.2 V with a ±5% tolerance. The device has a total power dissipation of 300 mW and supports a junction temperature range from -55 °C to +150 °C. Key electrical parameters include a maximum reverse current of 10 µA at 5 mA test current, a differential resistance of 3 Ω, and a diode capacitance of 4 pF. It is qualified according to AEC-Q101 for automotive applications.

Feature Summary

• Dual common anode configuration within a compact SOT-23 plastic package
• Qualified according to AEC-Q101 standards for automotive use
• Wide operating temperature range suitable for harsh environments

Applications

• General regulation functions
• Automotive electronic circuits

Procurement Notes

Verify the specific suffix 'QR' against the manufacturer's latest documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the component matches the required AEC-Q101 qualification status if used in automotive designs. Cross-reference the marking code 'UL%' on the physical device to confirm authenticity and correct voltage rating before integration into production lines.

Selection Notes

Select this part when a dual-diode solution is required in a minimal footprint. The C-series offers approximately ±5% tolerance, which is suitable for general-purpose regulation where tighter precision is not critical. Consider the 300 mW total power dissipation limit and thermal resistance values when designing heat management strategies for dense PCB layouts.

Part Context

This component belongs to the BZB84-Q series, which provides various Zener voltage options ranging from 2.4 V to 75 V. All variants share the same SOT-23 package and dual common anode topology. The series is designed to replace single diodes in space-constrained applications while providing two independent regulation paths or logic functions.

Replacement Considerations

Direct replacements within the same family include other BZB84-Q variants with different voltage ratings but identical pinouts and packages. Verify that any substitute maintains the AEC-Q101 qualification if automotive reliability is required. Single-diode equivalents like the BZX84 series require circuit redesign due to different pin configurations.
