Description
The LCA126 is a normally open (1-Form-A) solid
state relay, with enhanced on-resistance, that 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
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.
Use the LCA126 to replace mechanical relays,
and gain the superior reliability associated with
semiconductor devices, which, because they have no
moving parts, offer faster, bounce-free switching in a
compact surface mount or through-hole package.
