Switching Characteristics of
Normally Open (Form A) Devices
The LCA110L is a normally open (1-Form-A) solid
state relay that uses optically coupled MOSFET
technology to provide 3750Vrms of input to output
isolation. Its efficient MOSFET switches and
photovoltaic die use Clare’s patented OptoMOS
architecture. A highly efficent, optically coupled
GaAIAs infrared LED controls the output.
Use the LCA110L to replace mechanical relays,
and gain the superior reliability associated with
semiconductor devices, which, because they have no
moving parts, can offer faster, bounce-free switching
in a more compact surface mount or through-hole
package.
