BC55-10PASX

Single Bipolar Transistors Overview

The BC55-10PASX is an NPN medium power transistor from the Nexperia BC55xPAS series, housed in a DFN2020D-3 (SOT1061D) leadless SMD package. It supports a collector-emitter voltage of 60 V and continuous collector current up to 1 A, with peak current capability of 2 A. The device offers a DC current gain range of 63 to 160 at IC = 150 mA and VCE = 2 V. Total power dissipation reaches 1.65 W on standard FR4 PCBs. Operating junction temperature spans -55 °C to +150 °C.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging format and reel specifications. Confirm that the component version matches the required automotive or non-automotive qualification status as defined in the latest product data sheet revision history.

Single Bipolar Transistors Selection Notes

Select this component when space-constrained designs require medium power handling in a leadless footprint. The exposed thermal pad facilitates efficient heat dissipation compared to conventional packages. Ensure the application operates within the specified 60 V collector-emitter voltage limit and respects the 1 A continuous current rating under appropriate thermal conditions.

Single Bipolar Transistors Part Context

This part belongs to the BC55xPAS series, which includes variants with different current gain selections such as BC55PAS and BC55-16PAS. All series members share the same DFN2020D-3 package and general electrical characteristics, differing primarily in their hFE binning ranges to suit specific amplification or switching requirements.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include BC55PAS and BC55-16PAS from the same Nexperia series. Verify that alternative gain bins meet the circuit design requirements before substitution.
