BZB984-C3V0,115

Overview

The Nexperia BZB984-C3V0,115 is a voltage regulator double diode housed in an SOT-663 ultra-small plastic surface-mount package. It features a nominal working voltage of 3.0 V with approximately 5% tolerance. The device provides a total power dissipation of up to 425 mW when two diodes are loaded and 265 mW for single-diode operation at temperatures ≤ 25 °C. Key electrical characteristics include a maximum forward voltage of 0.9 V at 10 mA, a reverse current of 10 µA at 1 mA, and a differential resistance of 80 Ω at 5 mA. The component operates within an ambient temperature range of -55 °C to +150 °C.

Feature Summary

• Dual diode configuration integrated into an ultra-small flat plastic SMD package
• Approximately 5% Zener voltage tolerance for precise regulation
• High thermal robustness with non-repetitive peak reverse power dissipation up to 40 W

Applications

• General voltage regulation functions

Procurement Notes

Verify the specific ordering suffix

Selection Notes

Select this component for designs requiring dual voltage references or protection channels within constrained board areas. Ensure the operating junction temperature remains within the specified limits to maintain performance. Consider the thermal resistance values when calculating heat dissipation for densely packed layouts.

Part Context

This part belongs to the BZB984 series, which offers a comprehensive range of nominal working voltages from 2.4 V to 15 V. All variants share the same SOT-663 package and general electrical characteristics, differing primarily in their specific Zener voltage ratings and corresponding marking codes.

Replacement Considerations

Compatible substitutes within the BZB984 series include BZB984-C2V4 through BZB984-C15. These parts share identical packaging and pin configurations but offer different nominal voltages. Verify that the alternative voltage rating meets the circuit requirements before substitution.
