http://edisontechcenter.org/semiconductors.html WebNov 8, 2024 · DIACs are switching and bi-directional devices. A Gate terminal is absent in such devices. Both polarities can switch ON DIACs making it bi-directional. Two Zener diodes are connected to form DIAC and can utilize to trigger TRIACs. Switching lights, Fluorescent lamps, and dimming applications use DIACs.

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. WebA DIAC operated with a DC voltage across it behaves exactly the same as a Shockley diode. With AC, however, the behavior is different from what one might expect. Because alternating current repeatedly reverses direction, DIACs will not stay latched longer than one-half cycle. If a DIAC becomes latched, it will continue to conduct current only ...
