The CPC1225N is a miniature single-pole, normally
open (1-Form-A) solid state relay that employs
Clare’s patented, optically isolated OptoMOS
architecture to provide 1500Vrms of input-to-output
isolation. A highly efficient GaAIAs infrared LED
controls the optically coupled output. The device
also complies with the Supplementary Isolation
requirements of EN/IEC 60950-1.
The CPC1225N uses Clare’s state of the art double
molded vertical construction to produce one of the
world’s smallest 4-pin relays. It offers board space
savings approaching 20% over the competitor’s
larger 4-pin SOP relay.
