Description
LCA127 is a 250V, 200mA, 10 ? , normally open
(1-Form-A) solid state relay featuring low on-resistance.
It uses optically coupled MOSFET technology to
provide 3750V rms of input to output isolation.
Features
? 3750V rms 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
? Surface Mount Tape & Reel Version Available
Its optically coupled outputs, which use the patented
OptoMOS architecture, are controlled by a highly
efficient GaAIAs infrared LED.
The LCA127 can be used to replace mechanical
relays, and offers the superior reliability associated
with semiconductor devices. Because it has no moving
parts, it offers faster, bounce-free switching in a more
compact surface mount or thru-hole package.
