Description
PACK OF 100 PIECES
The BC557A is a PNP bipolar junction transistor (BJT) housed in a TO-92 package. This transistor is tailored for handling a collector current of up to 100mA, positioning it as suitable for low-power applications. It is capable of withstanding collector-to-emitter voltages up to 45V, enabling its use in a diverse range of circuit designs. The hFE (current gain) for the BC557A lies between 110 and 220, showcasing its capability to amplify signals effectively. Commonly employed in general-purpose amplification and switching, particularly where moderate voltage and low current are involved, the BC557A is a preferred choice. Its TO-92 package is a standard through-hole mounting design, widely used for its convenience in various electronic circuits. The BC557A transistor is frequently utilized in applications such as audio amplifiers, signal processing, and control circuits, where precise and efficient signal amplification is necessary.
