Overview
The Nexperia BZB784-C9V1-QX is a low-power voltage regulator double diode housed in an SOT323 (SC-70) surface-mounted device plastic package. It features a nominal Zener voltage of 9.1 V with a tolerance of approximately ±5%. The component has a total power dissipation rating of 350 mW and operates within a junction temperature range of -55 °C to +150 °C. Electrical characteristics include a maximum reverse current of 500 nA at 6 V reverse bias, a differential resistance of 40 Ω typ/100 Ω max at 5 mA test current, and a temperature coefficient of 5.2 mV/K typ/15 mV/K max. The device is qualified according to AEC-Q101 standards.
Feature Summary
- Dual common anode configuration for compact circuit design
- Qualified for automotive applications under AEC-Q101 standards
- Low forward voltage drop for efficient operation
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 reel specifications. Confirm that the automotive qualification status aligns with the target application requirements before finalizing procurement decisions.
Selection Notes
Select this component when a dual-diode voltage reference or protection solution is required in space-constrained designs. Ensure the operating current remains within limits to maintain the specified voltage tolerance and thermal performance characteristics.
Part Context
This part belongs to the BZB784-Q series, which offers a comprehensive range of nominal working voltages from 2.4 V to 15 V. All selections in this series share the same SOT323 package and are designed for high-density circuit implementations requiring reliable voltage regulation.
Replacement Considerations
Direct replacements must match the SOT323 package, 9.1 V nominal voltage, and dual common anode configuration. Verify that any substitute component meets the same AEC-Q101 automotive qualification and thermal dissipation ratings.
