Thyristor or Silicon Controlled Rectifier is well known as SCR. This device have four layers, three junctions and three terminals. Three terminals of SCR are gate, anode and cathode. Gate is located close to cathode. Like in PN junction diode, anode and cathode terminal makes thyristor or “silicon controlled rectifier” a RECTIFIER. Gate terminal controls …
