BZB984-C4V7,115

Overview

The Nexperia BZB984-C4V7,115 is a voltage regulator double diode housed in an SOT663 ultra-small plastic surface-mounted device package. It features two common-anode Zener diodes with a nominal working voltage of 4.7 V and a tolerance of approximately 5%. The total power dissipation is rated at 425 mW when both diodes are loaded, or 265 mW for single-diode operation. Key electrical parameters include a maximum forward voltage of 0.9 V at 10 mA, a reverse current of 3 µA at test conditions, and a differential resistance of 80 Ω. The device operates within a temperature range of -55 °C to +150 °C.

Feature Summary

• Dual common-anode configuration in an ultra-small flat plastic SMD package
• Total power dissipation up to 425 mW for compact high-density designs
• Approximately 5% Zener voltage tolerance across the E24 series range

Applications

• General regulation functions
• ESD and surge protection

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details such as reel size or tape-and-reel specifications. Ensure that the component version matches the required production data sheet revision. Confirm that the non-automotive qualification status aligns with the intended application environment before finalizing procurement orders.

Selection Notes

Select this component for applications requiring dual voltage references or protection circuits within space-constrained layouts. The SOT663 package offers a footprint suitable for high-density PCB designs. Consider the thermal resistance characteristics when designing heat dissipation paths, particularly if operating near the maximum power dissipation limits under continuous load conditions.

Part Context

This part belongs to the Nexperia BZB984 series of voltage regulator double diodes. The series provides a comprehensive range of nominal working voltages from 2.4 V to 15 V in the same SOT663 package. This standardization allows designers to implement consistent layout footprints while adjusting voltage requirements by simply changing the part number within the same family.

Replacement Considerations

Direct replacements within the BZB984 series require matching the Zener voltage and tolerance. Other Nexperia dual Zener families like BZB84 or BZX884 utilize different packages (SOT23 or SOD882) and cannot be pin-compatible substitutes without PCB redesign.
