BZB84-B3V6,215

Overview

The Nexperia BZB84-B3V6,215 is a dual Zener diode in a SOT23 (TO-236AB) plastic surface-mounted package. It features a dual common anode configuration with two tolerance series options. The nominal working voltage is 3.6 V with a ±2% tolerance. Key electrical parameters include a maximum reverse current of 5 µA at IZ=5 mA and a differential resistance of 90 Ω. Total power dissipation is rated at 300 mW per device. The component operates within a junction temperature range of -55 °C to +150 °C and is qualified to the AEC-Q101 standard for automotive applications.

Feature Summary

• Dual common anode configuration integrating two Zener diodes in a single compact SOT23 package
• Automotive qualification compliant with AEC-Q101 standards for high reliability
• Tight voltage tolerance available in ±2% and ±5% series for precision regulation
• Small plastic surface-mount design suitable for dense circuit layouts

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm manufacturing origin and compliance status. Ensure the selected variant matches the required voltage tolerance class for the intended application. Cross-reference the pinout diagram with the PCB footprint design to guarantee correct orientation during assembly. Confirm that the thermal management strategy aligns with the specified junction-to-ambient resistance values under expected operating conditions.

Selection Notes

Select this component when a dual Zener solution with a common anode is required in a small form factor. The B-series designation indicates a tighter ±2% voltage tolerance compared to the C-series. Consider the total power dissipation limit of 300 mW shared between the two diodes when designing the biasing network. Verify that the operating voltage range falls within the specified limits for stable Zener breakdown characteristics.

Part Context

This part belongs to the Nexperia BZB84 series of dual Zener diodes. The series offers a wide range of nominal working voltages from 2.4 V to 75 V. All variants share the same SOT23 package outline and pinning configuration. The series is designed to provide cost-effective voltage regulation solutions for general-purpose electronic applications requiring compact packaging.

Replacement Considerations

Direct replacements must match the SOT23 package, dual common anode configuration, and 3.6 V nominal voltage. Verify that any substitute component meets or exceeds the 300 mW total power dissipation rating and maintains compatibility with the AEC-Q101 qualification if automotive use is required.
