MOTOROLA SEMICONDUCTOR TECHNICAL DATA Triacs Silicon Bidirectional Triode Thyristors . . . designed primarily for full-wave ac control applications, such as solid-state relays, 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. Blocking Voltage to 800 .
