PBSS4160PANS-QX

Overview

The PBSS4160PANS-QX is a dual NPN Breakthrough In Small Signal (BISS) transistor manufactured by Nexperia. It operates with a maximum collector-emitter voltage of 60 V and a continuous collector current of 1 A per transistor, supporting peak currents up to 1.5 A. The device utilizes a DFN2020D-6 (SOT1118D) leadless package measuring 2 x 2 x 0.65 mm. Key electrical characteristics include a typical DC current gain (hFE) ranging from 70 to 430 depending on current levels, and a transition frequency (fT) of 175 MHz. The component features an exposed heat sink for thermal management and is qualified under the AEC-Q101 standard.

Feature Summary

• Very low collector-emitter saturation voltage for high energy efficiency
• High collector current capability with excellent current gain at elevated loads
• Exposed heat sink providing superior thermal and electrical conductivity
• AEC-Q101 automotive qualification ensuring reliability in demanding environments

Applications

• Load switch circuits
• Battery-driven devices
• Power management systems
• Charging circuits
• LED lighting applications

Procurement Notes

Verify the specific ordering suffix '-QX' against official Nexperia documentation to confirm its exact impact on packaging or lot traceability. Ensure that the procurement channel provides valid AEC-Q101 certification records. Confirm that the delivered components match the DFN2020D-6 physical dimensions and marking codes specified in the datasheet.

Selection Notes

Select this component when a dual NPN configuration is required within a compact footprint. The BISS technology offers lower power dissipation compared to standard small-signal transistors. Consider the DFN2020D-6 package for improved thermal performance via the exposed pad. Verify that the 60 V rating and 1 A current limits align with the target circuit requirements.

Part Context

This part belongs to the Nexperia PBSS4160 series of low VCEsat BISS transistors. It serves as the NPN/NPN variant within this family. Complementary configurations are available, including the PNP/PNP type PBSS5160PAPS and the NPN/PNP type PBSS4160PANPS. All variants share similar electrical characteristics optimized for power efficiency.

Replacement Considerations

Direct replacements must maintain the dual NPN topology and DFN2020D-6 package. Evaluate alternatives based on matching VCEO ratings of 60 V and comparable hFE curves. Ensure any substitute also meets AEC-Q101 standards if automotive application compliance is required.
