Triacs, also known as symmetric thyristors( eng. triac – triode for alternating current) are semiconductors from the group of thyristors. Triacs are designed using a five-layer structure and they have bidirectional adjustable conduction.
The five-layer structure with four transitions between them can be regarded as a combination of two thyristors. The opening of the two thyristors is done by impulses of the control current Ia with the same polarity. The bidirectional function of the triacs makes them broadly applicable in AC contactless regulators, for controlling low-power inductive loads, dimmable lighting fixtures, etc.
Vikiwat Ltd. offers a wide range of triacs and thyristors at competitive prices.
