SCR means Silicon Controlled Rectifier. This device belongs to the family THYRISTORS. Thyristors denotes a family of semiconductor devices used for power control in DC and AC system. At present , the use of SCR is well spread and so vast that the word thyristor becomes synonymous with SCR. In construction, it is a pnpn device .
A Thyristor is a Silicon Controlled Rectifier (SCR) which is functionally similar to a transistor. When voltage is applied to the gate, the SCR turns on (forward voltage onl â¦ y) and conducts. thyristor is a solid state three terminal electronic power  switch with two power terminals which carry the operational part of  the device current and one gate or trigger â¦ terminal which is used  to switch on the thyristor when required.
