The BCX55-16-QX is an NPN medium power transistor from the Nexperia BCX55-Q series, housed in a SOT89 (SC-62) surface-mounted plastic package. It features a collector-emitter voltage of 60 V and a continuous collector current of 1 A, with a peak pulse current capability of 2 A. The device offers three DC current gain selections; the -16 variant provides a minimum hFE of 100 at IC = 150 mA. It includes an exposed heatsink for thermal management and is qualified to AEC-Q101 standards.
Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact binning and packaging configuration. Ensure that the selected component meets the required automotive qualification standards and thermal dissipation requirements for the intended PCB footprint design.
Select this component when a robust NPN transistor with high current handling and automotive reliability is required. The exposed pad design necessitates proper thermal management on the PCB. Verify that the chosen gain bin aligns with the circuit's amplification or switching requirements.
This part belongs to the BCX55-Q series of NPN transistors designed for general-purpose and automotive use. It complements the BCX52-Q PNP counterpart. The series utilizes a flat lead SMD package optimized for heat transfer through the collector pad.
