Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details and reel specifications. Ensure the component matches the required current gain binning, as the BC55-10 variant specifies a defined hFE range distinct from other series members. Confirm compliance with RoHS directives and automotive qualification status prior to integration into final designs.

Single Bipolar Transistors Selection Notes

Select this component when a compact footprint with high thermal efficiency is required for NPN switching or amplification tasks. The exposed pad design facilitates superior heat dissipation compared to traditional packages. Consider the specific hFE binning requirements for linear applications, as gain variations exist within the series. Validate PCB layout compatibility with the DFN2020D-3 footprint and side-wettable flank soldering requirements.

Single Bipolar Transistors Part Context

This part belongs to the BC55xPAS-Q series, which includes complementary PNP variants and different gain selections. The series utilizes the DFN2020D-3 package to reduce PCB area while maintaining medium power handling capabilities. It serves as a modern replacement for older through-hole or larger surface-mount transistors in space-constrained consumer and automotive electronics.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include BC55PAS-Q and BC55-16PAS-Q from the same series, differing primarily in DC current gain ranges. Verify pinout compatibility and thermal resistance characteristics when replacing legacy components with similar voltage and current ratings but different package styles.
