BZB784-C10-QX

Overview

The Nexperia BZB784-C10-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 10 V with a ±5% tolerance range (9.4 V to 10.6 V). The device has a total power dissipation of 350 mW and operates within a junction temperature range of -55 °C to +150 °C. Key electrical characteristics include a maximum reverse current of 200 nA at 7 V, a differential resistance of 50 Ω typ, and a non-repetitive peak reverse current of 3.0 A for 100 µs pulses.

Feature Summary

• Dual common anode configuration suitable for compact circuit designs
• Qualified according to AEC-Q101 for automotive applications
• Low-power operation with approximately 5% Zener voltage tolerance

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 the component meets the required AEC-Q101 qualification standards if intended for automotive use. Cross-reference the marking code '9G' with the datasheet to validate authenticity upon receipt.

Selection Notes

Select this component when a dual-diode Zener solution is required in a small SOT323 footprint. The 10 V breakdown voltage fits within the E24 range of 2.4 V to 15 V. Consider the thermal resistance values if multiple devices are mounted closely on the PCB. Verify that the forward voltage and reverse leakage current meet the specific circuit requirements at the operating temperature.

Part Context

The BZB784-C10-QX belongs to the BZB784-Q series of low-power voltage regulator double diodes. This series offers various nominal voltages from 2.4 V to 15 V in the same SOT323 package. The '-Q' designation indicates AEC-Q101 qualification, distinguishing it from standard commercial variants while maintaining identical physical dimensions and pinout configurations.

Replacement Considerations

Direct substitutes within the same series include other BZB784-Cxx-Q types with different voltage ratings. Non-series equivalents may include single Zener diodes if dual functionality is not required, though package compatibility must be verified.
