BZB784-C11,115

Overview

The Nexperia BZB784-C11,115 is a voltage regulator diode designed for low-power applications. It features a nominal Zener voltage of 11 V with a tolerance of approximately ±5%. The device is housed in an SOT-323 (SC-70) surface-mount package, providing a compact solution for high-density circuit designs. Key electrical parameters include a maximum reverse leakage current of 200 nA and a Zener impedance of 20 ohms at a test current of 5 mA. The component supports a total power dissipation of up to 350 mW and operates within a temperature range from -65 °C to +150 °C.

Feature Summary

• Compact SOT-323 surface-mount package suitable for space-constrained designs
• Wide operating temperature range extending to +150 °C
• Normalized E24 series tolerance for consistent performance

Applications

• General regulation and voltage reference functions
• Over-voltage protection in small-scaled circuits

Selection Notes

Select this component when a compact voltage reference or regulator is required in an SOT-323 package. Ensure the 11 V nominal voltage aligns with circuit requirements and that the 350 mW power dissipation capability is sufficient for the intended thermal environment. Verify compatibility with the ±5% tolerance specification.

Part Context

This part belongs to the BZB784 series of low-power voltage regulator diodes from Nexperia. The series offers a comprehensive range of breakdown voltages and is designed for customized protection in high-density electronic applications. The BZB784-C11 variant specifically provides an 11 V reference point within this family.

Replacement Considerations

Compatible substitutes include other SOT-323 packaged Zener diodes with similar 11 V ratings and power dissipation capabilities, such as those from the BZX84 series if package adaptation is acceptable, or equivalent parts from other manufacturers offering SC-70 packages.
