It is a type of thyristor which operates as a unidirectional switch, handling large power levels efficiently. Since its introduction in the late 1950s, the silicon controlled rectifier has become indispensable in motor control, AC-DC conversion, and phase regulation. The SCR has assumed paramount importance in electronics because it can be produced in versions to handle currents upto several thousand amperes. . Decrease the size of your overall design while increasing power density and efficiency! VDS (max. TI PROVIDES TECHNICAL AND RELIABILITY DATA (INCLUDING DATA SHEETS), DESIGN RESOURCES (INCLUDING REFERENCE DESIGNS), APPLICATION OR OTHER DESIGN. . A Silicon Controlled Rectifier is a 3 terminal and 4 layer semiconductor current controlling device. It is made up of. . This allows a smaller gate current (forward or reverse) to exert a greater degree of control over conduction from cathode to anode, with the PNP transistor's latched state being more dependent upon the NPN's than vice versa. The Gate-Turn-Off thyristor is also known by the name of Gate-Controlled. .
