Overview
The Nexperia BZB84-C22-QR is a dual voltage regulator diode in a SOT-23 surface-mount package. It features a common anode configuration with two independent cathodes. The device provides a nominal Zener voltage of 22 V with approximately ±5% tolerance. Total power dissipation is rated at 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 component is qualified according to AEC-Q101 standards for automotive applications.
Feature Summary
- Dual common anode configuration within a compact SOT-23 plastic package
- Qualified according to AEC-Q101 for automotive environment reliability
- High non-repetitive peak reverse power dissipation capability
Applications
- General regulation functions
- Automotive electronic circuits
Procurement Notes
Verify the specific suffix and marking code against official Nexperia documentation before ordering. Confirm that the C-series tolerance aligns with circuit requirements. Ensure the SOT-23 footprint matches the design layout. Check for any recent datasheet revisions that may affect pinning or thermal characteristics.
Selection Notes
Select this component when dual voltage references are required in a single small package. The C-series offers standard tolerance suitable for general-purpose regulation. Verify that the 300 mW total power dissipation meets the thermal budget of the application. Consider the common anode topology for shared reference designs.
Part Context
This part belongs to the BZB84-Q series of dual voltage regulator diodes. The series covers nominal voltages from 2.4 V to 75 V. Both B (±2%) and C (±5%) tolerance options are available. All variants share the same SOT-23 package and AEC-Q101 qualification status.
Replacement Considerations
Single-channel Zener diodes like the BZX84-C22-QR can replace one half of the device if the second channel is unused. Other BZB84-Q series parts with different voltages are pin-compatible but require voltage verification.
