BZB84-B4V7,215

Overview

The Nexperia BZB84-B4V7,215 is a dual Zener diode in a SOT-23 (TO-236AB) surface-mount package. It features a dual common anode configuration with two independent cathodes. The nominal Zener voltage is 4.7 V with a ±2% tolerance series. Key electrical parameters include a total power dissipation of 300 mW, a maximum reverse leakage current of 3 µA at 25 °C, and a differential resistance of 500 Ω. The device operates within a junction temperature range of -55 °C to +150 °C and is qualified to AEC-Q101 standards for automotive applications.

Feature Summary

• Dual common anode configuration providing two independent Zener diodes in a single compact package.
• Automotive-grade qualification compliant with AEC-Q101 stress test standards.
• High thermal stability suitable for demanding environments with a junction temperature rating up to 150 °C.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm manufacturing origin and compliance status. Ensure the component matches the required tolerance series for your design specifications. Cross-reference the datasheet revision history to confirm the document version aligns with your procurement requirements.

Selection Notes

Select this component when a dual Zener solution is required in a small SMD footprint. 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 the PCB layout for adequate heat dissipation.

Part Context

This part belongs to the Nexperia BZB84 series of general-purpose dual Zener diodes. The series offers a wide range of nominal working voltages from 2.4 V to 75 V in the E24 range. All variants share the same SOT-23 package and dual common anode topology, differing primarily in voltage ratings and tolerance classes.

Replacement Considerations

Direct replacements within the same family include other BZB84-Bxxxx types with different voltage ratings but identical package and tolerance specifications. Verify pinout compatibility and thermal characteristics before substituting with components from other manufacturers.
