BZB784-C6V8-QX

Overview

The Nexperia BZB784-C6V8-QX is a low-power voltage regulator double diode housed in a SOT323 (SC-70) surface-mount package. It features a nominal working voltage of 6.8 V with a tolerance of approximately ±5%. The device has a total power dissipation rating of 350 mW and operates within an ambient temperature range of -55 °C to +150 °C. Key electrical characteristics include a maximum reverse current of 2 µA at 4 V, a differential resistance of 30 Ω typ / 80 Ω max, and a non-repetitive peak reverse current capability of 6.0 A.

Feature Summary

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

Applications

• General regulation functions
• ESD protection
• Surge protection

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the component meets all required automotive qualification standards if intended for such environments. Cross-reference the marking code '9C' with the datasheet to validate authenticity upon receipt.

Selection Notes

Select this component when a dual-diode Zener solution is required in a small SC-70 footprint. Ensure the application voltage aligns with the 6.8 V nominal rating and consider the thermal resistance values for heat dissipation in dense layouts. Verify that the operating current stays within the specified limits to maintain the ±5% voltage tolerance.

Part Context

This part belongs to the BZB784-Q series, which provides a comprehensive range of low-power voltage regulator double diodes. The series offers various nominal voltages from 2.4 V to 15 V, all sharing the same SOT323 package and AEC-Q101 qualification. It serves as a standardized solution for space-constrained automotive and industrial designs requiring dual voltage references or protection channels.

Replacement Considerations

Other members of the BZB784-Q series (e.g., BZB784-C6V2-Q, BZB784-C7V5-Q) share identical pinouts and packages but differ in Zener voltage. Non-Q versions like the BZB784-C6V8 lack automotive qualification. Verify functional equivalence before substituting.
