BZB84-C18,215

Overview

The Nexperia BZB84-C18,215 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 18 V with a ±5% tolerance. Total power dissipation is 300 mW per device. Key electrical parameters include a maximum reverse current of 45 μA at IZ=1 mA and a temperature coefficient ranging from 12.4 to 16.0 mV/K at IZ=5 mA. Non-repetitive peak reverse power dissipation reaches 40 W for pulses ≤300 μs.

Feature Summary

• Dual common anode configuration providing two independent Zener diodes in one package
• Qualified for automotive applications under AEC-Q101 standards
• Compact SOT-23 plastic package suitable for high-density surface-mounted designs

Applications

• General regulation functions

Procurement Notes

Verify the specific ordering suffix

Selection Notes

Select the BZB84 series for dual Zener requirements in space-constrained designs. The C suffix indicates a ±5% voltage tolerance, suitable for general-purpose regulation where tighter precision is not required. Ensure the total power dissipation limit of 300 mW is respected across both diodes during operation.

Part Context

This component belongs to the BZB84 series of dual Zener diodes manufactured by Nexperia. The series offers a wide range of nominal voltages from 2.4 V to 75 V. The BZB84-C18 variant specifically provides an 18 V breakdown voltage with standard commercial tolerance, packaged in the widely used SOT-23 form factor.

Replacement Considerations

Compatible substitutes within the same family include BZB84-B18,215 for tighter ±2% tolerance or other BZB84-C variants for different voltage levels. Verify pinout compatibility as all BZB84 types share the same SOT-23 pinning.
