LCA220 is a normally open, double-pole, single-throw
(2-Form-A) solid state relay that has two optically
coupled MOSFET switches controlled by a common
input signal. It is provided in an 8-pin package, and
employs optically coupled MOSFET technology to
provide 3750Vrms of input to output isolation.

Features
Its optically coupled outputs, which use the patented
OptoMOS architecture, are controlled by a highly
efficient infrared LED.
• 3750Vrms Input/Output Isolation
• Low Drive Power Requirements
• Greater Reliability than Electromechanical Relays
• FCC Compatible
Common-input OptoMOS relays can replace standard
dual, single-throw relays in a variety of applications.
The common-input relay eliminates the need to make
a second circuit connection when both poles are
controlled by the same signal.
• VDE Compatible
• No EMI/RFI Generation
• Small 8-Pin Package
• Surface Mount Tape & Reel Version Available
• Flammability Rating UL 94 V-0
Approvals
• UL Recognized Component: File # E76270
• TUV EN 62368-1: Certificate # B 082667 0008
Applications
• Telecommunications
• Telecom Switching
• Tip/Ring Circuits
• Modem Switching (Laptop, Notebook, Pocket Size)
