BZB84-C12,215

Overview

The Nexperia BZB84-C12,215 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 Zener voltage is 12 V with a ±5% tolerance range of 11.4 V to 12.7 V at IZ = 5 mA. Key electrical parameters include a maximum reverse current of 25 μA, 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.

Feature Summary

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

Applications

• General regulation functions

Procurement Notes

Verify the specific suffix '215' against the manufacturer's latest documentation to confirm the exact tape-and-reel packaging quantity and manufacturing origin code. Ensure the component status remains active before finalizing procurement plans, as product availability may change without notice.

Selection Notes

Select this part when a dual Zener solution with a shared anode is required in a small footprint. The C-series offers a wider ±5% voltage tolerance compared to the B-series. Verify that the 300 mW total power dissipation rating meets the thermal requirements of the target application environment.

Part Context

This component belongs to the Nexperia BZB84 series of general-purpose dual Zener diodes. The series provides various nominal working voltages ranging from 2.4 V to 75 V in the E24 range. All variants share the same SOT-23 package and dual common anode topology, differing primarily in voltage ratings and tolerance grades.

Replacement Considerations

Other BZB84-C12 variants are available with different tolerances or suffixes. Single Zener diodes like the BZX84-C12 serve as functional alternatives if dual configuration is not needed.
