BZB784-C2V7-QX

Overview

The Nexperia BZB784-C2V7-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 2.7 V with a tolerance of approximately ±5%. The device supports a total power dissipation of up to 350 mW and operates within a junction temperature range of -55 °C to +150 °C. Key electrical characteristics include a maximum reverse current of 20 µA, a differential resistance of 300 Ω typ at IZ=5 mA, and a capacitance of 450 pF at 1 MHz. It is qualified according to AEC-Q101 for automotive applications.

Feature Summary

• Dual common-anode configuration providing two independent voltage regulation channels in a compact footprint.
• Qualified for automotive environments under the AEC-Q101 standard.
• Offers narrow working-voltage tolerances suitable for precision reference circuits.

Applications

• General voltage regulation functions
• ESD protection circuits
• Surge protection

Procurement Notes

Verify the specific suffix 'QX' against official Nexperia documentation to confirm packaging details such as reel size or tape width. Confirm that the 'Q' designation aligns with the required AEC-Q101 qualification status for your specific project constraints before finalizing orders.

Selection Notes

Select this component when dual-channel regulation is required in space-constrained designs. Ensure the operating current stays 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 expands the standard BZB784 line with automotive-grade qualification. The series covers nominal voltages from 2.4 V to 15 V, all sharing the same SC-70 plastic package and pinout structure for design flexibility.

Replacement Considerations

Check for BZB784-C2V7 without the Q suffix if automotive qualification is not strictly required, noting potential differences in reliability testing standards. Other BZB784 variants share the same package but differ in voltage ratings.
