BC550C Description

Short technical summary and product information.

The NXP Semiconductors BC550C is an NPN bipolar junction transistor (BJT) designed for general-purpose applications. It is housed in a compact TO-92 (SOT54) plastic package, suitable for through-hole mounting.

Key electrical characteristics include a maximum collector-emitter voltage (VCEO) of 45 V and a continuous collector current (IC) of up to 100 mA. The transistor also offers a low noise figure, making it ideal for low noise stages in audio frequency equipment. Its PNP complement is the BC560.

With a thermal resistance of 250 K/W (junction to ambient) when mounted on an FR4 printed-circuit board, the BC550C is designed for moderate power dissipation. The datasheet provides detailed specifications for DC current gain (hFE), saturation voltages (VCEsat, VBEsat), and capacitances (Cc, Ce), along with transition frequency (fT).

This component is a reliable choice for designers seeking a general-purpose NPN transistor with established performance characteristics for audio and other signal processing applications.
