Simple thyristor circuit

WebbA thyristor is a four-layer semiconductor device, consisting of alternating P-type and N-type materials (PNPN). A thyristor usually has three electrodes: an anode, a cathode and a gate, also known as a control electrode. The most common type of thyristor is the silicon-controlled rectifier (SCR). Webb2. Low driving power and a simple drive circuit due to the input MOS gate structure. It canbe easily controlled as compared to current controlled devices (thyristor, BJT) in high voltage and high current applications. 3. Wide SOA. It has superior current conduction capability compared with the bipolar transistor.
