SABTRAFO electrical components Germany SABTRAFO model SABTRAFO price

SABTRAFO electrical components are semiconductor transistors, 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. Transistors are one of the basic semiconductor components, featuring current amplification capabilities, and are core components in electronic circuits. A transistor is formed by fabricating two closely spaced PN junctions on a single semiconductor substrate; these two PN junctions divide the entire semiconductor into three parts: the middle part is the base region, and the two sides are the emitter region and the collector region, arranged
