BZB784-C6V2-QX

Overview

The Nexperia BZB784-C6V2-QX is a voltage regulator double diode in the BZB784-Q series, housed in an SOT323 (SC-70) surface-mounted plastic package. It features a nominal working voltage of 6.2 V with a tolerance of approximately ±5%. The device has a total power dissipation of ≤350 mW and operates within a temperature range of -55 °C to +150 °C. Key electrical characteristics include a maximum reverse current of 3 µA at VR = 4 V, a differential resistance of 40 Ω typ., and a capacitance of 200 pF max. at f = 1 MHz. It is qualified according to AEC-Q101 for automotive applications.

Feature Summary

• Dual common anode configuration suitable for compact circuit designs
• Qualified for automotive applications under AEC-Q101 standards
• Low-power operation with high thermal stability

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 that the component matches the required AEC-Q101 qualification status if intended for automotive use. Cross-reference the marking code '9B' with the datasheet to validate authenticity upon receipt.

Selection Notes

Select this component when a dual Zener diode solution is required in a small SOT323 footprint. The 6.2 V nominal voltage and ±5% tolerance make it suitable for precise reference applications. Consider the low reverse leakage current and moderate differential resistance for efficient voltage clamping in sensitive signal paths.

Part Context

This part belongs to the BZB784-Q series of low-power voltage regulator double diodes from Nexperia. The series offers a wide range of nominal voltages from 2.4 V to 15 V, all sharing the same SOT323 package and AEC-Q101 qualification. The 'Q' designation indicates automotive-grade reliability, while the 'C' denotes the specific voltage tolerance class.

Replacement Considerations

Direct substitutes within the same family include other BZB784-C variants with different nominal voltages, provided the pinout and package remain identical. For equivalent performance, verify that any replacement maintains the same AEC-Q101 qualification and SOT323 form factor.
