• Dual common anode configuration suitable for compact circuit designs
• AEC-Q101 qualified for automotive electronics reliability
• Small plastic SMD package optimized for high-density mounting

Applications

• General regulation functions
• Voltage reference circuits
• Over-voltage protection

Procurement Notes

Verify the specific ordering suffix matches the required manufacturing origin and tape-and-reel specifications. Confirm that the ±2% tolerance variant aligns with design requirements. Ensure compatibility with standard SOT-23 footprints during PCB layout verification.

Selection Notes

Select this part for applications requiring dual Zener functionality in a minimal footprint. Consider the 24 V nominal voltage and 300 mW total dissipation limits. Verify thermal management needs against the junction-to-ambient resistance values provided in the datasheet for the target operating environment.

Part Context

This component belongs to the Nexperia BZB84 series of dual Zener diodes. The series offers various nominal voltages from 2.4 V to 75 V in the SOT-23 package. The 'B' suffix indicates the ±2% voltage tolerance grade, distinguishing it from the 'C' grade which offers ±5% tolerance.

Replacement Considerations

Direct substitutes within the same series include BZB84-C24,215 for looser tolerance requirements. Other Nexperia single Zener diodes in SOT-23 may serve as functional replacements if dual configuration is not strictly required.
