BC550CG

Single Bipolar Transistors Overview

The onsemi BC550CG is an NPN silicon epitaxial planar transistor housed in a TO-92 (SOT54) plastic package. It features a maximum collector current of 100 mA and a collector-emitter voltage rating of 45 V. The device offers a minimum DC current gain (hFE) of 110, with a transition frequency of 1 MHz. Absolute maximum ratings include a collector-base voltage of 50 V, an emitter-base voltage of 5 V, and a total power dissipation of 500 mW at 25°C. The component operates within a junction temperature range of -65°C to +150°C.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'C' against the manufacturer's latest datasheet to confirm the exact hFE binning requirements for your design. Ensure the TO-92 package dimensions match your PCB footprint constraints. Confirm RoHS compliance status if required by your manufacturing standards, as older batches may differ.

Single Bipolar Transistors Selection Notes

Select this component when low noise performance is critical in the signal path. Compare the 45V VCEO rating against your circuit's peak voltage swings to ensure adequate margin. Consider the 100mA Ic limit for load driving capabilities. Evaluate thermal management needs given the 500mW power dissipation limit in free air.

Single Bipolar Transistors Part Context

The BC550CG belongs to the BC550 series of NPN general-purpose transistors manufactured by onsemi. This series is widely used in consumer electronics and industrial control systems. It serves as a complement to PNP devices like the BC560. The TO-92 package provides a cost-effective solution for low-power discrete applications.

Single Bipolar Transistors Replacement Considerations

BC550BTA and BC550CBU are functionally similar NPN transistors from onsemi with comparable electrical ratings. Verify pinout compatibility and specific hFE ranges before substitution.
