BZB784-C11-QX

Overview

The Nexperia BZB784-C11-QX is a voltage regulator double diode housed in an SOT323 (SC-70) surface-mounted package. It features a nominal working voltage of 11 V with a ±5% tolerance, operating between 10.4 V and 11.6 V at a test current of 5 mA. The device has a maximum reverse leakage current of 100 nA at 8 V and a differential resistance of 150 Ω. Total power dissipation is rated at 350 mW for dual-diode loading. It is qualified to AEC-Q101 standards for automotive use.

Feature Summary

• Dual common-anode configuration within a compact SC-70 plastic package
• Automotive-grade qualification compliant with AEC-Q101 standards
• Approximately 5% Zener voltage tolerance across the E24 range

Applications

• General regulation functions
• ESD protection
• Surge protection

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details such as reel or cut tape specifications. Ensure the component meets the required AEC-Q101 automotive qualification criteria for the intended application environment before finalizing procurement orders.

Selection Notes

Select this component when a dual-diode Zener solution is required in space-constrained designs. The SOT323 package supports high-density circuit layouts. Verify that the 11 V breakdown voltage aligns with system requirements and that the 350 mW power dissipation rating accommodates the thermal conditions of the target PCB footprint.

Part Context

This part belongs to the BZB784-Q series, which provides low-power voltage regulator double diodes. The series offers various nominal voltages from 2.4 V to 15 V in the same SOT323 package, allowing designers to standardize on a single package type while adjusting voltage ratings through different model suffixes.

Replacement Considerations

Direct replacements include other BZB784-C11 variants such as BZB784-C11 without the -Q suffix if automotive qualification is not mandatory. Cross-series alternatives like BZX884 or BZX84 require verification of pinout compatibility and package dimensions.
