SEHILL electrical components Germany SEHILL model SEHILL price

SEHILL electrical components are semiconductor triodes, also known as bipolar junction transistors or crystal triodes. They 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. The triode is one of the basic semiconductor components, featuring current amplification capability, and is a core component 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 middle part is the base region, and the two sides are the emitter region and the collector region. The arrangement method
