BZB784-C8V2-QX

Overview

The Nexperia BZB784-C8V2-QX is a low-power voltage regulator double diode housed in an SOT323 (SC-70) surface-mount package. It features a nominal Zener voltage of 8.2 V with a tolerance of approximately ±5%. The device has a total power dissipation rating of up to 350 mW and operates within a temperature range of -55 °C to +150 °C. Key electrical characteristics include a maximum reverse current of 700 nA at 5 V reverse bias, a differential resistance of 40 Ω typ., and a forward voltage of 0.9 V max. at 10 mA.

Feature Summary

• Dual common-anode configuration for compact circuit designs
• Qualified according to AEC-Q101 for automotive applications
• Low leakage current and tight working-voltage tolerances

Applications

• General regulation functions
• ESD and surge protection

Procurement Notes

Verify the specific suffix 'QX' against official Nexperia documentation to confirm reel packaging details and ensure compliance with automotive qualification standards. Confirm that the marking code '9E' matches the intended component revision before finalizing procurement orders.

Selection Notes

Select this component when dual voltage regulation or protection is required in space-constrained designs. Ensure the operating current remains within limits to maintain the specified ±5% voltage tolerance. Verify thermal management requirements given the 350 mW total dissipation limit in the SOT323 package.

Part Context

This part belongs to the BZB784-Q series, which offers a comprehensive range of nominal voltages from 2.4 V to 15 V. All variants share the same SOT323 footprint and AEC-Q101 qualification, allowing for design flexibility while maintaining consistent mechanical and reliability profiles across different voltage requirements.

Replacement Considerations

Direct substitutes within the same series include BZB784-C7V5-Q and BZB784-C9V1-Q if voltage adjustments are permissible. Cross-series replacements require verification of pin compatibility and power dissipation ratings.
