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.

The rapid advancement of artificial intelligence (AI) is transforming industries across the globe, and the world of electronic components is no exception. From smarter…
