The LCA110 is a normally open (1-Form-A) Solid
State Relay which uses optically coupled MOSFET
technology to provide 3750Vrms of input to output
isolation.
120
On-Resistance (max)
35
Its optically coupled outputs, which use the patented
OptoMOS architecture, are controlled by a highly
efficient infrared LED.
Features
• 3750Vrms Input/Output Isolation
• Low Drive Power Requirements (TTL/CMOS
Compatible)
• Greater Reliability than Electromechanical Relays
• No EMI/RFI Generation
The LCA110 can be used to replace mechanical
relays, and offers the superior reliability associated with
semiconductor devices.
• Small 6-Pin Package
