Overview
The Nexperia BZB84-C56-QR is a dual voltage regulator diode in the BZB84-Q series, housed in an SOT-23 surface-mount package. It features a dual common anode configuration with two independent cathodes. The nominal Zener voltage is 56 V with a tolerance of approximately ±5 %. Total power dissipation is limited to 300 mW, while non-repetitive peak reverse power dissipation reaches 40 W per diode. Operating junction temperature ranges from -55 °C to +150 °C. The device is qualified according to AEC-Q101 for automotive applications.
Feature Summary
- Dual common anode configuration providing two independent regulation channels within a single compact package.
- Qualified according to AEC-Q101 standards for use in demanding automotive electronic environments.
- High non-repetitive peak reverse power dissipation capability supports transient surge protection scenarios.
Applications
- General voltage regulation functions
- Automotive circuit design
Procurement Notes
Verify the specific ordering suffix and marking code against the manufacturer's official documentation before finalizing procurement. Confirm that the component meets all required environmental and automotive qualification standards for the intended application environment.
Selection Notes
Select this component when a dual-channel voltage reference or regulation solution is required in a space-constrained SOT-23 footprint. Ensure the operating current remains within limits to maintain the specified differential resistance and temperature coefficient characteristics for stable performance.
Part Context
This part belongs to the BZB84-Q series of dual voltage regulator diodes manufactured by Nexperia. The series offers various nominal working voltages ranging from 2.4 V to 75 V in both ±2 % (B-series) and ±5 % (C-series) tolerances, all sharing the same SOT-23 package and automotive qualification profile.
Replacement Considerations
Other parts within the BZB84-Q series may serve as functional substitutes if the voltage tolerance and nominal Zener voltage requirements align with the specific circuit design parameters.
