Silicon Controlled Rectifiers (SCRs) are three-terminal devices that behave like rectifier diodes, with an added ability to block current flow in the forward direction until a control signal is applied. Most commonly used for controlling AC utility power, SCRs are also known as thyristors, though this latter term is also sometimes applied to other related devices.
