BZB984-C3V6,115

Overview

The Nexperia BZB984-C3V6,115 is a voltage regulator double diode housed in an SOT-663 ultra-small plastic surface-mount package. It features two cathodes and one common anode, providing nominal working voltages within the E24 range of 2.4 V to 15 V. The device offers approximately 5% Zener voltage tolerance and supports a total power dissipation of up to 425 mW when both diodes are loaded at 25 °C. Key electrical parameters include a maximum forward voltage of 0.9 V at 10 mA, a reverse current of 5 µA at 1 V, and a temperature coefficient of -1.9 mV/K at 5 mA test current.

Feature Summary

• Dual-diode configuration with a common anode for compact circuit integration
• Ultra-small SOT-663 plastic surface-mount package design
• Approximately 5% Zener voltage tolerance for precise regulation

Applications

• General voltage regulation functions
• ESD protection circuits
• Surge protection applications

Procurement Notes

Verify the specific ordering suffix matches the required packaging format before purchase. Confirm that the component meets the thermal resistance requirements for your specific PCB footprint and copper area. Ensure the application environment stays within the specified ambient temperature limits to maintain safe operating conditions.

Selection Notes

Select this component when space constraints require a dual-diode solution in an SOT-663 package. Verify that the 425 mW total power dissipation rating accommodates the expected load currents. Check the temperature coefficient characteristics against the thermal stability requirements of the target application environment.

Part Context

This part belongs to the BZB984 series of low-power voltage regulator diodes from Nexperia. The series provides various nominal working voltages ranging from 2.4 V to 15 V. All variants share the same SOT-663 package outline and pinning configuration, differing primarily in their Zener voltage specifications and associated marking codes.

Replacement Considerations

Direct substitutes must match the SOT-663 package, dual-diode common-anode configuration, and 3.6 V nominal voltage. Verify equivalent power dissipation ratings and tolerance levels. Cross-reference with other manufacturers offering similar ultra-small dual Zener arrays if supply chain constraints exist.
