The nominal Zener voltage is 3.9 V with a ±5% tolerance. Total power dissipation is 300 mW per device, while non-repetitive peak reverse power dissipation reaches 40 W. Operating junction temperature ranges from -55 °C to +150 °C. The component is AEC-Q101 qualified for automotive applications.

Feature Summary

• Dual Zener diodes in a single compact SOT-23 plastic package
• Common anode configuration for space-saving circuit designs
• AEC-Q101 qualified for high-performance automotive applications

Applications

• General regulation functions

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm manufacturing origin and tape-and-reel specifications. Ensure compatibility with standard SOT-23 footprints during PCB layout. Confirm that the dual common anode topology aligns with the intended circuit schematic before finalizing procurement orders.

Selection Notes

Select this component when a dual Zener solution with a shared reference point is required in a small footprint. The C-series offers a wider voltage tolerance compared to the B-series. Verify that the 300 mW total power dissipation rating meets the thermal requirements of the target application environment.

Part Context

This part belongs to the BZB84 series of dual Zener diodes manufactured by Nexperia. The series provides various nominal working voltages ranging from 2.4 V to 75 V. It utilizes the SOT-23 package to support high-density surface-mounted designs in consumer and automotive electronics.

Replacement Considerations

Check for other BZB84 variants with different voltage ratings or tolerance codes if electrical parameters do not match. Verify pinout compatibility for the common anode configuration before substituting with similar dual Zener components from other manufacturers.
