Overview
The Nexperia BZB784-C7V5-QX is a low-power voltage regulator double diode housed in an SOT323 (SC-70) surface-mount package. It features a nominal working voltage of 7.5 V with a tolerance of approximately ±5%. The device operates within a junction temperature range of -55 °C to +150 °C and supports a total power dissipation of up to 350 mW. Key electrical characteristics include a maximum reverse current of 1 µA at VR = 5 V, a differential resistance ranging from 30 Ω to 80 Ω, and a diode capacitance of 150 pF measured at 1 MHz. It is qualified according to AEC-Q101 for automotive applications.
Feature Summary
- Dual common-anode configuration providing two independent Zener diodes in a compact footprint
- Automotive-grade qualification compliant with AEC-Q101 standards
- Wide operating temperature range suitable for demanding environments
Applications
- General regulation functions
- ESD protection circuits
- Surge protection applications
Procurement Notes
Verify the specific suffix 'QX' against official Nexperia documentation to confirm tape-and-reel packaging details. Ensure the component meets the required AEC-Q101 automotive qualification standards for your target application environment before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener configuration is required in a small SC-70 package. Verify that the 7.5 V nominal breakdown voltage aligns with circuit requirements. Confirm thermal management capabilities are sufficient for the expected power dissipation levels in the final design.
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 package and automotive qualification profile, allowing for consistent supply chain management across different voltage reference needs.
Replacement Considerations
Direct substitutes within the BZB784-Q series include other voltage variants such as BZB784-C6V8-Q or BZB784-C8V2-Q if voltage adjustment is permissible. Cross-brand replacements require verification of pinout compatibility, package dimensions, and AEC-Q101 compliance.
FAQ
What is the marking code for the BZB784-C7V5-Q?
The marking code for the BZB784-C7V5-Q type number is 9D.
What is the non-repetitive peak reverse current for this device?
The non-repetitive peak reverse current (IZSM) is 4.0 A under conditions of tp = 100 µs square wave at Tamb = 25 °C.
How does the temperature coefficient vary with working current?
For the BZB784-C7V5-Q, the typical temperature coefficient ranges from 6 mV/K to 15 mV/K depending on the Zener current (IZ), transitioning from negative to positive values as current increases.
