TCA 785

Bipolar IC

PG-DIP-16-1

Type

TCA 785

Ordering Code

Q67000-A2321

Package

PG-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.
