Description
LAA127 is a 250V, 200mA, 10 dual normally open
(1-Form-A) Solid State Relay that comprises two
independently controlled, optically coupled MOSFET
switches. The combination of super efficient MOSFET
switches and photovoltaic die provides 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 single-pole 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.
