BZB84-B12,215

Overview

The Nexperia BZB84-B12,215 is a dual Zener diode in a SOT-23 (TO-236AB) plastic surface-mounted device package. It features a dual common anode configuration with two tolerance series options. The nominal working voltage is 12 V with a ±2% tolerance. Key electrical parameters include a maximum reverse current of 0.1 µA at IZ=5 mA, a differential resistance of 8 Ω, and a temperature coefficient of 6.0 mV/K. Total power dissipation is 300 mW, with a non-repetitive peak reverse power dissipation of 40 W. Operating junction temperature ranges from -55 °C to +150 °C.

Feature Summary

• Dual common anode configuration for compact circuit design
• Automotive Electronics Council (AEC) Q101 qualified
• Small plastic SMD package suitable for surface-mounted applications

Applications

• General regulation functions

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm manufacturing origin and exact compliance status. Confirm that the component matches the required AEC-Q101 qualification standards for the intended application environment before finalizing procurement orders.

Selection Notes

Select this component when a dual Zener diode with a common anode is required in a small SOT-23 package. Ensure the 12 V nominal voltage and ±2% tolerance align with the circuit requirements. Verify thermal management capabilities given the 300 mW total power dissipation limit in free air conditions.

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. The 'B' suffix indicates a tighter voltage tolerance of ±2%, while the 'C' suffix denotes ±5% tolerance. All variants share the same SOT-23 package and general characteristics.

Replacement Considerations

Direct replacements within the same family include other BZB84-B variants with different voltage ratings but identical package and tolerance specifications. Cross-family replacements require matching the dual common anode configuration, SOT-23 package, and equivalent electrical parameters such as power dissipation and voltage tolerance.
