DIAC: Construction, Operation, and Applications - WellPCB
WEBDIAC is an acronym that stands for Diode for Alternating Current. And the solid-state device features two-junction semiconductors and three layers. At first glance, you may mistake the DIAC’s structure for a transistor. But the difference is that the former doesn’t have a terminal at the base layer. Hence, it’s a two-terminal device (A1 & A2).
Diacs, Triacs and Thyristers - HyperPhysics
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.
