IXYS Integrated Circuits Division/Littelfuse's CPC1010N is a miniature, single-pole, normally open (1-Form-A) solid-state relay in a 4-pin SOP package. The relay employs optically coupled MOSFET technology to provide 1500 V_RMS of input-to-output isolation. The efficient MOSFET switches and photovoltaic die use IXYS Integrated Circuits Division/Littelfuse's patented OptoMOS^® architecture while the optically coupled output is controlled by a highly efficient infrared LED.

IXYS/Littelfuse's state-of-the-art double-molded vertical construction packaging makes the CPC1010N one of the world’s smallest relays. It offers board space savings over the competitor’s larger 4-pin SOP relay.
