FAQ about Thyristors - SCRs
-
1. What are the uses of SCR?
The main uses of SCR (silicon controlled rectifier) include the following aspects:
Power switch application: SCR is suitable for medium and high voltage AC power control applications, such as lighting adjustment, voltage regulator and motor control. It can control high-power devices at high voltage and trigger the opening and closing of devices through the control terminal (gate), which is suitable for occasions that require frequent switching.
Automatic control system: SCR is a high-power driving device in the automatic control system, which can realize the control of high-power equipment with low-power controls. It is widely used in AC and DC motor speed control systems, power control systems and follow-up systems.
Selective catalytic reduction system: In the automotive field, SCR refers to the selective catalytic reduction system, which is used to reduce NOx in engine exhaust to meet higher emission regulations.
Circuit protection: In some cases, SCRs may be formed unintentionally in integrated circuits. When they are triggered, they may cause circuit failures, even reliability problems and damage. Therefore, this situation needs to be avoided when designing circuits.

2. What is the difference between SCR and SCS?
The main difference between SCR (thyristor) and SCS (thyristor switch) lies in their functions and application scenarios.
Function and application scenarios
SCR (thyristor):
Function: SCR is a three-terminal four-layer semiconductor device that is mainly used to control the conduction and cutoff of current. It can only control conduction, not shutdown, and is a semi-controlled device.
Application scenarios: SCR is often used in overvoltage protection circuits, dimming circuits, etc., to protect and adjust the circuit by controlling voltage and current.
SCS (Silicon Controlled Switch):
Function: SCS is a silicon controlled switch, mainly used for switch action control.
Application scenarios: SCS is often used for simple switch action control, such as household appliances, industrial equipment, etc.
Why are thyristors so popular among other SCR devices?
The main reasons why thyristors (SCRs) are so popular among other SCR devices include their high efficiency, reliability, and wide application scenarios.
Efficiency and reliability
Thyristors have the following advantages:
Efficiency: Thyristors can achieve efficient power control, have high efficiency, can reduce energy loss, and improve the overall performance of the equipment.
Reliability: Thyristors have a simple structure and do not require complex manufacturing processes, so they are low in cost and have a long service life.

3. Is SCR a DC switch or an AC switch?
AC switch
SCR (Silicon Controlled) is mainly used for AC switching. SCR, or thyristor, is a high-power semiconductor device, mainly used in phase control, rectification, voltage regulation, contactless switching and other applications in AC circuits.
Working principle of SCR
SCR is a four-layer, three-terminal PNPN structure semiconductor device, composed of alternating P-type and N-type semiconductor materials, forming three main terminals: anode, cathode and gate. In the absence of a gate trigger signal, SCR behaves as a reverse-biased PN junction, and even if there is a voltage between the anode and cathode, SCR will not conduct. When the gate receives a sufficiently large trigger signal, the SCR will change from the cut-off state to the on state.
