Description:
The BC558 is a Bi-Polar PNP transistor designed for use in audio amplification applications and as a switching element. It has a high current gain of up to 800, allowing for efficient amplification. With a peak collector current of 200mA and continuous current of 100mA, it is ideal for low power switching applications. The transistor operates by biasing the base pin, which allows it to switch between open (Reverse Bias) and closed (Forward Bias) states. This transistor is available in a TO-92 package for easy integration into circuits.
