Package
P-DIP-16-1
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.
