BZB84-C56,215

Overview

The Nexperia BZB84-C56,215 is a dual Zener diode in a SOT-23 (TO-236AB) surface-mount package. It features a dual common anode configuration with two independent cathodes. The nominal working voltage is 56 V with a ±5% tolerance range of 52.0 V to 60.0 V. Total power dissipation is 300 mW per device. Key electrical parameters include a maximum reverse current of 200 μA at IZ=0.5 mA, a differential resistance of 425 Ω at IZ=2 mA, and a temperature coefficient ranging from 52.2 to 63.8 mV/K at IZ=2 mA. Non-repetitive peak reverse power dissipation is 40 W.

Feature Summary

• Dual common anode configuration for compact circuit design
• Qualified for automotive applications under AEC-Q101 standards
• Small plastic SMD package suitable for automated surface mounting

Selection Notes

Select this component when a dual Zener array with a common anode is required in a small footprint. The C-series offers approximately ±5% tolerance, suitable for general-purpose regulation where tighter precision is not critical. Ensure the operating voltage stays within the specified limits to maintain reliability.

Part Context

This part belongs to the BZB84 series of dual Zener diodes manufactured by Nexperia. The series provides various breakdown voltages from 2.4 V to 75 V in the E24 range. The BZB84-C variant specifically denotes the ±5% tolerance option, distinguishing it from the B-series (±2%) and A-series (±1%).

Replacement Considerations

Direct replacements must match the dual common anode configuration, SOT-23 package, and 56 V nominal voltage. Verify that substitute parts meet or exceed the 300 mW power dissipation and AEC-Q101 qualification requirements if used in automotive contexts.
