BC55PAS-QX

Single Bipolar Transistors Overview

The BC55PAS-QX is a 60 V, 1 A NPN medium power bipolar junction transistor (BJT) from Nexperia. It utilizes an ultra-thin DFN2020D-3 (SOT1061D) leadless surface-mount package with visible and solderable side pads. Key electrical specifications include a collector-emitter voltage of 60 V, collector-base voltage of 60 V, and continuous collector current of 1 A. The device features an exposed heat sink for thermal management and supports Automatic Optical Inspection (AOI). It is qualified to the AEC-Q101 standard for automotive reliability.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix and ordering code against official Nexperia documentation to ensure correct configuration. Confirm AEC-Q101 qualification status if automotive compliance is required. Check for any recent product change notifications or longevity program updates regarding supply availability. Ensure the DFN2020D-3 package dimensions match the target PCB footprint design constraints.

Single Bipolar Transistors Selection Notes

Select this component when a compact, high-current NPN transistor is needed for space-constrained designs. The exposed pad design aids in thermal dissipation compared to traditional packages. Consider the 60 V rating for general-purpose switching and amplification tasks. Verify that the leadless package handling requirements align with the manufacturing assembly process capabilities.

Single Bipolar Transistors Part Context

This part belongs to the BC5xPAS-Q series of medium power transistors designed for modern surface-mount technology. It serves as the NPN variant within a family that includes complementary PNP types like the BC54PAS-Q. The series emphasizes reduced PCB area requirements while maintaining robust performance characteristics suitable for both industrial and automotive electronic systems.

Single Bipolar Transistors Replacement Considerations

Direct substitutes may include other Nexperia parts in the same DFN2020D-3 package with matching voltage and current ratings. Verify pinout compatibility and thermal resistance values before substitution. Cross-reference with equivalent industry-standard BJT packages if form-factor changes are permissible.
