LCA220
DS-LCA220-R6
LCA220 is a common input 1- Form 2A solid state relay
which has two independent optically couple MOSFETs
controlled by a common input signal. The efficient MOS-
FET switches and photovoltaic die use Clare’s patented
OptoMOS architecture to provide 3750 VRMS of input to
output isolation. The optically coupled input is controlled
by highly efficient GaAIAs infrared LEDs. Common input
OptoMOS relays can replace standard dual pole relays in
a variety of applications. The common input relay elimi-
nates the need to make an external circuit connection
when both poles are controlled by a common signal.

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.
