| Description | The BC557B is a general-purpose PNP bipolar junction transistor designed for low-noise amplification and switching applications. It features a maximum collector-emitter voltage of -45 V and supports continuous collector currents up to approximately -100 mA. The “B” gain group indicates a medium DC current gain (hFE) typically ranging from 200 to 450, making it suitable for amplification circuits. The device provides low noise performance and reliable switching characteristics. The BC557B is commonly used in audio amplification, signal processing, switching circuits, complementary transistor pairs (with BC547B), and general-purpose electronic applications. |
