The PLA191 is a 1-Form-A solid state relay that uses opti-
cally coupled relay technology to provide an enhanced
5000V isolation barrier between the input and the output
of the relay. The efficient MOSFET switches use Clares
patented OptoMOS architecture. The optically coupled
input is controlled by a highly efficient GaAIAs infrared LED.

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.
