BZB84-B7V5,215

Overview

The Nexperia BZB84-B7V5,215 is a dual Zener diode in a SOT-23 (TO-236AB) surface-mount package. It features a nominal working voltage of 7.5 V with a ±2% tolerance series designation. The device has a total power dissipation of 300 mW and operates within an ambient temperature range of -55 °C to +150 °C. Key electrical parameters include a maximum reverse current of 1 μA at IZ=5 mA, a differential resistance of 80 Ω, and a temperature coefficient of 2.5 mV/K. It is AEC-Q101 qualified for automotive applications.

Feature Summary

• Dual common anode configuration for compact circuit design
• Automotive-grade qualification compliant with AEC-Q101 standards
• High precision voltage regulation with ±2% tolerance option

Applications

• General regulation functions
• Voltage reference circuits
• Over-voltage protection in automotive environments

Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel packaging format. Confirm the manufacturing origin code corresponds to the designated production site. Ensure the component status is listed as Production rather than Obsolete or Preliminary before finalizing supply agreements.

Selection Notes

Select this variant when a precise 7.5 V reference is required with tight tolerance constraints. The dual common anode structure allows for independent control of two regulated lines from a single package. Consider the thermal resistance characteristics for high-density PCB layouts.

Part Context

This component belongs to the BZB84 series of general-purpose dual Zener diodes. The series offers a wide range of nominal voltages from 2.4 V to 75 V across E24 values. The 'B' suffix indicates the tighter ±2% tolerance band compared to the standard C series.

Replacement Considerations

Direct substitutes within the same family include BZB84-C7V5,215 for looser tolerance requirements. Other Nexperia dual Zener variants in SOT-23 packages may serve as functional replacements if pinout compatibility is maintained.
