LCA110L is a current-limited, normally open
(1-Form-A) solid state relay that uses optically
coupled MOSFET technology to provide 3750Vrms of
input to output isolation.

On-Resistance (max)
35
Its optically coupled outputs, which use the patented
OptoMOS architecture, are controlled by a highly
efficient GaAIAs infrared LED.
Features
• Built-in Current Limiting
• 3750Vrms Input/Output Isolation
• Low Drive Power Requirements
(TTL/CMOS Compatible)
• No Moving Parts
• High Reliability
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.
