Thyristors or silicon controlled rectifiers (SCR) as they are sometimes known may appear to be unusual electronics components in many ways, but they are particularly useful for controlling power circuits.

As such these electronics components are used for many power control applications, often where current and voltage levels are relatively high. Thyristors may also be used in lower power applications including light control, as well as for power supply protection and many other applications. Thyristors are simple to use and cheap to buy, making them an ideal option for many circuits.

The idea for the thyristor is not new. The idea for the device was first put forward in 1950 by William Shockley, one of the inventors of the transistor. Although some later investigation of the device was undertaken by others a couple of years later, it was not until the early 1960s when they became available. After the introduction of the thyristor, they soon became popular for electronic switching and power supply circuits.
