What is a Silicon Controlled Rectifier (SCR)?

A Silicon Controlled Rectifier (SCR) is a four-layer semiconductor device that acts as an electrically controlled switch. It is a type of thyristor, which is widely used in various electronic and power control applications. The SCR allows the flow of current in only one direction, similar to a diode, but it can also be triggered into conduction by applying a gate signal. SCR is made up of silicon material and has the ability to handle high power levels. It offer fast switching characteristics making it suitable for controlling large amounts of electrical power with high efficiency.

The basic structure of an SCR consists of three terminals: 

  • Anode (A) is the positive terminal.
  • Cathode (K) is the negative terminal.
  • Gate (G) is used to control the device.

When a positive voltage is applied to the anode with respect to the cathode and no gate current is applied, the SCR remains in the "off" state and does not conduct. However, when a positive gate current is applied while the anode-cathode voltage is positive, the SCR enters the "on" state and conducts current. Once triggered into conduction, the SCR remains conducting even if the gate current is removed until the anode-cathode voltage drops below a certain threshold, typically referred to as the "holding current."

The SCR is ideal for power control circuits, such as in motor speed control, lighting control, voltage regulation, and power supplies. It is often utilized for applications requiring high current and voltage handling capabilities, as SCRs can handle several kilovolts and hundreds or thousands of amperes.
