1 page ![]() Semiconductor Group 1 TCA 785 This phase control IC is intended to control thyristors, triacs, and transistors. The trigger pulses can be shifted within a phase angle between 0 ˚ and 180 ˚. Typical applications include converter circuits, AC controllers and three-phase current controllers. This IC replaces the previous types TCA 780 and TCA 780 D.
