Diacs, Triacs and Thyristers - GSU

WebTriac Tutorial. A Triac is a high-speed solid-state device that can switch and control AC power in both directions of a sinusoidal waveform. Both the thyristor and triac can be used to control lamps, motors, or heaters etc. However, one of the problems of using a thyristor for controlling such circuits is that like a diode, the “thyristor ... WebA diac is a form of solid-state switch used to switch AC voltage; it belongs to the class of switches known as thyristers.It is like a junction transistor without a base lead (it is a two-lead device) and accomplishes its switching action by breakdown at a certain voltage. There are also four layer devices with a similar mode of operation known as four-layer diodes. npl-copyright-statement
