Overview
The Nexperia BZB84-C2V4-QR is a dual voltage regulator diode from the BZB84-Q series, housed in an SOT23 surface-mount package. It features a dual common anode configuration with two independent cathodes. The nominal Zener voltage is 2.4 V with a ±5% tolerance range (2.20 V to 2.60 V). Total power dissipation is rated at 300 mW, and non-repetitive peak reverse power dissipation reaches 40 W. Operating temperatures span from -55 °C to +150 °C. The device is AEC-Q101 qualified 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, making it suitable for demanding automotive electronic environments.
- Small SOT23 plastic package designed for efficient surface-mounted circuit board layouts.
Applications
- General voltage regulation functions
- Automotive electronics circuits
Procurement Notes
Verify the specific suffix against official Nexperia documentation to confirm reel specifications and packaging details. Ensure the ordering code matches the required tolerance series and package variant before finalizing procurement orders.
Selection Notes
Select this component when a dual-channel voltage reference is required in a minimal footprint. The C-series offers approximately 5% tolerance, which suits general-purpose applications where tighter precision is not critical. Confirm thermal management requirements align with the 300 mW total dissipation limit.
Part Context
This part belongs to the BZB84-Q series of dual voltage regulator diodes manufactured by Nexperia. The series provides various breakdown voltages ranging from 2.4 V to 75 V in standardized E24 values. All variants share the same SOT23 package and dual common anode topology.
Replacement Considerations
Direct substitutes include other BZB84-Q series parts with identical pinouts but different voltage ratings, such as BZB84-B2V4-QR for tighter tolerance. Cross-brand replacements require verification of pin compatibility and electrical parameters.
