Preferred Device
Triacs
Silicon Bidirectional Thyristors
Designed primarily for full-wave ac control applications, such as light dimmers, motor controls, heating controls and power supplies; or wherever full–wave silicon gate controlled solid–state devices are needed. Triac type thyristors switch from a blocking to a conducting state for either polarity of applied main terminal voltage with positive or negative gate triggering.
