Thyristor, which belongs to the field of power devices, is a kind of power semiconductor switching device. SCR is its abbreviation. According to its operating characteristics, SCR can be divided into (SCR) (TRIAC). It is a component consisting of a PNPN four-layer semiconductor and has three electrodes, an anode A, a cathode K, and a control electrode G. The thyristor can achieve AC contactless control in the circuit, control large current with a small current, and does not generate sparks when controlled like a relay, and has quick action, long life, and good reliability. In the speed, dimming, voltage regulator, temperature control and other various control circuits have its presence. SCRs are unidirectional and bidirectional, with different symbols.

As a power switching element, thyristors can replace contactors and relays for high switching frequency applications. Therefore, thyristor components are widely used in circuits of various electronic devices and electronic products, and are used for controllable rectification, inverter, frequency conversion, voltage regulation, and contactless switches. Dimming lights, speed-adjusting fans, heating and cooling air conditioners, water heaters, televisions, refrigerators, washing machines, cameras, sound sets, voice-activated circuits, timing controllers, sensor lights, Christmas light controllers, automatic door circuits, and toys in household appliances Thyristor devices are widely used in industrial control fields such as devices, power tool products, radio remote control circuits, and cameras. In these application circuits, the SCR components are mostly used for controllable rectification, inverter, frequency conversion, voltage regulation, and non-contact switches.
