BZB84-B11,215

Overview

The Nexperia BZB84-B11,215 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 and one shared anode pin. The nominal working voltage is 11 V with a ±2% tolerance. Total power dissipation is 300 mW per device. Key electrical parameters include a maximum reverse current of 10 μA at IZ=5 mA, a differential resistance of 20 Ω, and a temperature coefficient of 5.4 mV/K. Non-repetitive peak reverse power dissipation reaches 40 W.

Feature Summary

• Dual common anode configuration for compact circuit design
• Qualified to AEC-Q101 automotive standards
• Small plastic SMD package suitable for high-density layouts

Applications

Selection Notes

Select this component when a dual Zener solution with a common anode is required in a small footprint. The B-series designation ensures tight ±2% voltage tolerance compared to the C-series. Ensure the application operates within the 300 mW total power dissipation limit and respects the junction temperature constraints defined in the thermal characteristics.

Part Context

This part belongs to the Nexperia BZB84 series of general-purpose Zener diodes. The series offers a wide range of nominal voltages from 2.4 V to 75 V in both B (±2%) and C (±5%) tolerance grades. All variants share the same SOT-23 package and dual common anode topology, allowing for consistent board layout across different voltage requirements.

Replacement Considerations

Other BZB84-B11 variants with different manufacturing origin suffixes are functionally equivalent. Single Zener diodes like the BZX84-B11 can replace one half of the device if the second channel is unused, though this increases board space.
