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. WebThyristors: It acts as a switch and remains off until the ___ reaches a certain value, turns on, and conducts. Thyristors: ___ continues until the current is reduced below a specified value. The 4-layer diode, also known as a ___ (SUS) or Shockley diode, is a class of devices constructed of four semiconductor layers.
