Description
LAA126L is a Dual 1 Form-A solid state relay that has
two independently controlled optically coupled
MOSFETs with an additional current limiting circuit.
The efficient MOSFET switches and photovoltaic die
use Clare’s patented OptoMOS architecture to provide
3750 V_RMS of input to output isolation. The optically
coupled inputs are controlled by highly efficient
GaAIAs infrared LEDs. Dual pole OptoMOS relays
provide a more compact design solution than discrete
single pole relays in a variety of applications. The dual
pole relays save board space by incorporating both
relays in a single 8-pin package.
