BC557C Description

Short technical summary and product information.

The BC557C from NXP Semiconductors is a PNP bipolar junction transistor (BJT) suitable for general-purpose switching and amplification tasks. It is housed in a compact TO-92 (SOT54) plastic package, making it ideal for through-hole mounting on printed circuit boards.

Key electrical characteristics include a maximum collector-emitter voltage (VCEO) of 45V and a continuous collector current (IC) of 100 mA. The transistor offers a DC current gain (hFE) ranging from 420 to 800 under typical test conditions (IC = -2 mA, VCE = -5V). Its collector-emitter saturation voltage (VCEsat) is a maximum of 300 mV at IC = -10 mA and IB = -0.5 mA.

With a maximum power dissipation of 500 mW at 25°C ambient temperature and a thermal resistance of 250 K/W, the BC557C is designed for moderate power applications. The operating temperature range is from -65°C to +150°C, ensuring reliability across various environmental conditions. Its NPN complement is the BC547.

This transistor is well-suited for a variety of electronic circuits requiring signal amplification or switching functions. The TO-92 package is common in through-hole designs, offering ease of assembly and a small footprint.
