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 3750V_rms of
input to output isolation.
The optically coupled outputs, which use the
patented OptoMOS architecture, are controlled by a
highly efficient GaAIAs 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.
