Multicomp Pro BC108C NPN Transistor, TO-18, 25V 200mA

The Multicomp Pro BC108C is a silicon NPN bipolar planar epitaxial transistor engineered for reliability in general-purpose amplification and switching applications. Featuring a low-power design with a collector-emitter voltage maximum of 25V, it is well-suited for a wide range of electronic circuits where stable performance is essential.

This transistor offers a continuous collector current of 200mA and a power dissipation rating of 600mW, making it a robust choice for low to medium power requirements. Its high DC current gain (hFE minimum of 420) ensures efficient signal amplification, while a transition frequency of 150MHz supports applications requiring good frequency response.

Housed in a classic TO-18 metal can package with three pins, the BC108C is designed for through-hole mounting, providing mechanical durability and excellent thermal characteristics. Its construction allows it to operate at temperatures up to 200°C, making it suitable for industrial environments.

Common applications include use in audio amplifiers, signal processing circuits, driver stages, and as a switch in digital logic interfaces. Its consistent performance and proven design make it a fundamental component for hobbyists, educators, and professional engineers alike.
