Description
The PLA143 is a single-pole, normally open (1-Form-A) solid state relay that uses optically coupled MOSFET technology to provide an enhanced input to output isolation of 4000Vrms.
Its optically coupled outputs, which use the patented OptoMOS architecture, are controlled by a highly efficient GaAIAs infrared LED.
The PLA143 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.
