It features a nominal Zener voltage of 3.6 V with a tolerance of ±5%. The device has a total power dissipation of 350 mW and operates within a junction temperature range of -55 °C to +150 °C. It includes two cathodes and one common anode. The component is qualified according to AEC-Q101 for automotive applications.
Feature Summary
- Dual-diode configuration with a common anode structure
- AEC-Q101 qualification for automotive reliability
- Compact SC-70 plastic surface-mount packaging
Applications
- General regulation functions
- ESD protection
- Surge protection
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current documentation to confirm tape-and-reel specifications and marking codes. Ensure that the selected variant matches the required automotive grade and package dimensions for your PCB layout. Cross-reference the part number with official Nexperia databases to validate availability and production status before finalizing procurement plans.
Selection Notes
Select this component when a dual Zener configuration is required in a small footprint. The BZB784-C3V6-QX provides a 3.6 V reference point with standard tolerance. Consider the thermal resistance values if multiple devices are mounted closely on the PCB. Verify that the operating current remains within the limits specified in the electrical characteristics table to maintain accuracy.
Part Context
This part belongs to the BZB784-Q series, which offers a comprehensive range of nominal working voltages from 2.4 V to 15 V. All variants in this series share the same SOT323 package and AEC-Q101 qualification. The series is designed for customized protection in small-scale, high-density circuit designs, providing narrow working-voltage tolerances across different voltage options.
Replacement Considerations
Other parts in the BZB784-Q series with different voltage ratings can replace this unit if the voltage requirement changes. Non-Q versions like BZB784-C3V6 may be considered if automotive qualification is not required.
