## **Features**
- 100% Solid State
- Small 6-Pin Package
- Low Drive Power Requirements (TTL/CMOS Compatible)
- High Reliability
- Arc-Free With No Snubbing Circuits
## **Description**
The LCA110 is a 1-Form-A Solid State Relay which uses optically coupled MOSFET technology to provide 3750Vrms of input to output isolation. The efficient MOSFET switches and photovoltaic die use Clare’s patented OptoMOS[®] architecture. The optically coupled output is controlled by a highly efficient GaAIAs infrared LED. The LCA110 can be used to replace mechanical relays and offers the superior reliability associated with semiconductor devices. Because they have no moving parts, they can offer faster, bounce-free switching in a more compact surface mount or though hole package.
- 3750Vrms Input/Output Isolation
- No EMI/RFI Generation
- Machine Insertable, Wave Solderable
- Surface Mount Tape & Reel Version Available
- Flammability classification rating of V-0

## **Manufacturing Information**
## **Soldering**
For proper assembly, the component must be processed in accordance with the current revision of IPC/JEDEC standard J-STD-020. Failure to follow the recommended guidelines may cause permanent damage to the device resulting in impaired performance and/or a reduced lifetime expectancy.
## **Washing**
Clare does not recommend ultrasonic cleaning or the use of chlorinated solvents.
