Description
LCB111 is a 350V, 120mA, 35, normally closed
(1-Form-B) solid state relay featuring high sensitivity.
It uses optically coupled relay technology to provide
a 3750Vrms isolation barrier between the input and
the output of the relay.
Its optically coupled outputs, which use the patented
OptoMOS architecture, are controlled by a highly
efficient GaAIAs infrared LED.
• Low Input Control Current: 2mA
• 3750Vrms Input/Output Isolation
• Low Drive Power Requirements (TTL/CMOS
Compatible)
• High Reliability
• Arc-Free With No Snubbing Circuits
• FCC Compatible
• VDE Compatible
• No EMI/RFI Generation
• Small 6-Pin Package
• Machine Insertable, Wave Solderable
• Tape & Reel, Surface Mount Version Available
The LCB111 can be used to replace mechanical
relays, and offers the superior reliability associated
with semiconductor devices. Because it has no moving
parts, it can offer faster, bounce-free switching in a
more compact surface mount or thru-hole package.
