BZB84-B5V1,215

Overview

The Nexperia BZB84-B5V1,215 is a dual Zener diode in a SOT-23 (TO-236AB) surface-mount package. It features a common anode configuration with two independent diodes. The nominal working voltage is 5.1 V with a ±2% tolerance. Total power dissipation is ≤300 mW per device, and non-repetitive peak reverse power dissipation is ≤40 W. Operating temperature ranges from -55 °C to +150 °C. It is AEC-Q101 qualified for automotive applications.

Feature Summary

• Dual Zener diodes in a single small plastic SMD package
• Common anode configuration for space-saving designs
• AEC-Q101 qualified for automotive reliability standards

Applications

• General regulation functions

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to ensure correct packaging and manufacturing origin details. Confirm that the component status remains active before finalizing design-in decisions. Cross-reference the marking code VH* with the official datasheet table to validate authenticity upon receipt.

Selection Notes

Select this part when a dual Zener solution with a common anode is required in a compact SOT-23 footprint. The 5.1 V nominal voltage and ±2% tolerance suit precision reference or clamping tasks. Ensure thermal constraints allow for the specified 300 mW total power dissipation limit under operating conditions.

Part Context

This component belongs to the BZB84 series of dual Zener diodes offered by Nexperia. The series provides various voltage options ranging from 2.4 V to 75 V in both ±2% and ±5% tolerance variants. All devices share the same SOT-23 package and general electrical characteristics, differing primarily in breakdown voltage and specific tolerance grades.

Replacement Considerations

Direct substitutes within the same family include other BZB84-Bxxx types with different voltage ratings but identical pinout and package. Verify compatibility if replacing with a different voltage; otherwise, check for equivalent dual Zener parts from other manufacturers offering similar SOT-23 dual configurations.
