The CPC1231N is a miniature 1-Form-B solid state
relay which uses optically coupled MOSFET
technology to provide 1500V
RMS
of input to output
isolation and is certifide for Supplemented Isolation in
accordance with EN60950. The efficient MOSFET
switches and photovoltaic die use Clare's patented
OptoMOS
architecture. The optically-coupled input
is controlled by a highly efficient GaAIAs infrared
LED. The CPC1231N uses Clare's state of the art
double molded vertical construction packaging to
produce the world's smallest 4 pin SOP relay. The
CPC1231N offers board space savings of at least
20% versus competitive 4 Pin SOP solid state relay.
UL Recognized Component: File #E76270
Certified to EN60950, Supplemental Isolation
