Preferred Device
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 anode voltage with positive or
negative gate triggering.
