Overview
The Nexperia BZB84-B3V0-QR is a dual voltage regulator diode in a SOT23 surface-mounted package. It features a nominal Zener voltage of 3.0 V with a ±2% tolerance (range 2.94 V to 3.06 V). The device has a total power dissipation of 300 mW and supports a non-repetitive peak reverse power dissipation of 40 W per diode. Operating temperatures range from -55 °C to +150 °C. Key electrical characteristics include a maximum forward voltage of 0.9 V at 10 mA, a reverse current of 600 μA at 5 mA, and a differential resistance of 95 Ω.
Feature Summary
- Dual common anode configuration for compact circuit design
- Qualified according to AEC-Q101 for automotive applications
- High non-repetitive peak reverse power dissipation capability
Applications
- General regulation functions
Procurement Notes
Verify the specific suffix 'QR' indicates reel packaging when sourcing. Confirm the 'B' designation corresponds to the ±2% tolerance series rather than the standard ±5% variant. Ensure the component matches the SOT23 footprint dimensions provided in the datasheet for PCB layout compatibility.
Selection Notes
Select this part for designs requiring precise voltage regulation within a tight tolerance band. The dual common anode structure allows for independent control of two regulated lines using a single shared ground reference. Consider the thermal resistance values when determining heat dissipation requirements in enclosed environments.
Part Context
This component belongs to the BZB84-Q series, which offers various Zener voltages from 2.4 V to 75 V. The 'B' suffix denotes the tighter ±2% tolerance version, while 'C' indicates approximately ±5%. All variants share the same SOT23 package and AEC-Q101 qualification status.
Replacement Considerations
Direct substitutes within the same series include BZB84-C3V0-Q for looser tolerance or other BZB84-Bxxx-Q variants for different voltage levels. Cross-brand replacements must match the SOT23-3 pinout and ensure equivalent power dissipation and temperature ratings.
