CPC1943G
DS-CPC1943G-R1
The CPC1943G is an AC Solid State Switch using optical
coupling with dual power SCR outputs to produce an
alternative to optocoupler and Triac circuits. The
CPC1943G switches are robust enough to provide a
blocking voltage of up to 400V. In addition, tightly con-
trolled zero cross circuitry ensures switching of AC loads
without the generation of transients. The input and output
circuits are optically coupled to provide 3750V of isolation
and noise immunity between control and load circuits. As
a result the CPC1943G is well suited for industrial envi-
ronments where electromagnetic interference could dis-
rupt the operation of electromechanical relays.

Electrical Characteristics
Absolute Maximum Ratings are stress ratings. Stresses in
excess of these ratings can cause permanent damage to
the device. Functional operation of the device at these or
any other conditions beyond those indicated in the opera-
tional sections of this data sheet is not implied. Exposure
of the device to the absolute maximum ratings for an
extended period may degrade the device and effect its
reliability.
