Description
The LCA127L is a current-limiting, 250V, 170mA, 15 ? ,
normally open (1-Form-A) solid state relay featuring
low on-resistance, which uses optically coupled
MOSFET technology to provide 3750V rms of input to
output isolation.
Features
? Current Limiting
? 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
Applications
? Telecommunications
? Telecom Switching
? Tip/Ring Circuits
Its optically coupled outputs, which use the patented
OptoMOS architecture, are controlled by a highly
efficient GaAIAs infrared LED.
LCA127L 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.
