LAA120 is a dual normally open (1-Form-A) Solid
State Relay that has two independently controlled,
optically coupled MOSFET switches. The MOSFET
switches and photovoltaic die use optically coupled
MOSFET technology to provide 3750V
rms
of input to
output isolation.
The optically coupled outputs, which use the patented
OptoMOS architecture, are controlled by a highly
efficient GaAIAs infrared LED.
This dual switch OptoMOS relay provides a more
compact design solution than discrete single-pole
relays in a variety of applications, and saves board
space by incorporating both switches in a single 8-Pin
package.
