BZB84-C4V3,215

Overview

The BZB84-C4V3,215 is a dual common anode voltage regulator diode manufactured by Nexperia. It features a nominal Zener voltage of 4.3 V with a ±5% tolerance. The device operates in the SOT-23-3 surface-mount package and dissipates up to 300 mW of power. Key electrical parameters include a maximum reverse leakage current of 3 µA, a Zener impedance of 80 Ohms at a test current of 5 mA, and a forward voltage of 900 mV. The component supports an operating temperature range from -55 °C to +150 °C.

Selection Notes

Select this component when a dual Zener configuration is required in a compact footprint. The 4.3 V breakdown voltage suits reference applications. Ensure the 300 mW power dissipation rating meets the thermal requirements of the target environment. Compare against single-diode alternatives if space permits.

Part Context

This part belongs to the BZB84 series, which represents dual common anode variants within Nexperia's broader BZX84 family of low-power voltage regulator diodes. While the standard BZX84 series offers single diodes in SOT-23 packages, the BZB84 variant integrates two junctions in one package to save board space. This series complements the BZX884 line, offering higher power handling than leadless packages while maintaining small form factors.

Replacement Considerations

Direct substitutes include other BZB84-C4V3 parts from different manufacturers or equivalent dual common anode Zener diodes in SOT-23 packages. Verify pinout compatibility and ensure the replacement maintains the 300 mW power rating and 4.3 V tolerance.
