CPC1945G

DS-CPC1945G-R1

The CPC1945G is a AC Solid State Switch using patent­ed waveguide coupling with dual power SCR outputs to
produce an alternative to optocoupler and Triac circuits.
The CPC1945G switches are robust enough to provide a
blocking voltage of up to 400V. In addition, tightly con­trolled 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 CPC1945G is well suited for industrial
environments where electromagnetic interference would
disrupt 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
operational 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.
