Bartec FEAM electrical components are semiconductor triodes, also known as bipolar junction transistors or crystal triodes, which are semiconductor devices that control current. Their function is to amplify weak signals into electrical signals with larger amplitudes, and they are also used as contactless switches. Triodes are one of the basic semiconductor components, featuring current amplification capabilities, and are core components in electronic circuits. A triode is formed by creating two closely spaced PN junctions on a single semiconductor substrate; these two PN junctions divide the entire semiconductor into three parts: the base region in the middle, and the emitter and collector regions on the sides.
