Description

LAA120 is a dual normally open (1-Form-A) Solid

State Relay that has two independently controlled,

optically coupled MOSFET switches. The MOSFET

switches and photovoltaic die use optically coupled

MOSFET technology to provide 3750Vrms of input to

output isolation.

The optically coupled outputs, which use the patented

OptoMOS architecture, are controlled by a highly

efficient 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.
