The BC158 is a general-purpose PNP Bipolar Junction Transistor (BJT) designed for low-level amplification and switching applications. It is manufactured using silicon technology and is supplied in a TO-18 metal package for through-hole mounting. The transistor is commonly used in audio circuits, signal amplification stages, control circuits, and general-purpose electronic designs.
Designed for reliable low-power operation, the BC158 supports a collector-emitter voltage of 25V and a maximum collector current of 100mA. Its electrical characteristics make it suitable for analog signal processing, switching applications, and small-signal amplification. The metal package provides mechanical durability and dependable thermal performance in a wide range of electronic circuits.
The BC158 is widely used in educational projects, prototype development, consumer electronics, and industrial electronic equipment. Its compact package and stable performance make it a practical choice for engineers, students, hobbyists, and circuit designers working with low-power transistor applications.
