Description
LAA125L is a dual normally open (1-Form-A) Solid
State Relay that has two independently controlled,
optically coupled MOSFET switches with an
additional current limiting circuit. The optically coupled
combination of MOSFET switches and photovoltaic die
provide 3750V_rms of input/output isolation.
The optically coupled outputs, which use patented
OptoMOS architecture, are controlled by a highly
efficient GaAIAs infrared LED.
This dual switch OptoMOS relay provides a more
compact design solution than discrete single-pole
relays in a variety of applications, and saves board
space by incorporating both switches in a single 8-Pin
package.
