BZB84-B2V7,215

Overview

The Nexperia BZB84-B2V7,215 is a dual Zener diode in a SOT-23 (TO-236AB) surface-mount package. It features a common anode configuration with two independent cathodes. The nominal Zener voltage is 2.7 V with a ±2% tolerance series 'B'. Key electrical parameters include a maximum reverse current of 20 µA at IZ=5 mA, a differential resistance of 600 Ω, and a temperature coefficient of -3.5 mV/K. Total power dissipation is 300 mW, with a non-repetitive peak reverse power dissipation of 40 W.

Feature Summary

Selection Notes

Select the BZB84-B2V7 variant when a tight ±2% voltage tolerance is required compared to the standard ±5% C-series options. Ensure the operating current aligns with the specified test conditions for optimal accuracy. Consider the thermal resistance characteristics if multiple devices are mounted closely on the PCB.

Part Context

This component belongs to the BZB84 series of general-purpose dual Zener diodes manufactured by Nexperia. The series offers a wide range of nominal working voltages from 2.4 V to 75 V in both ±2% and ±5% tolerance grades. All variants share the same SOT-23 plastic package and common anode pinout structure.

Replacement Considerations

Direct replacements within the same family include BZB84-C2V7,215 for a wider ±5% tolerance or other BZB84-Bxxx types for different voltage levels. Cross-package alternatives like the BZX84W series require verification of pin compatibility and power dissipation limits.
