The CPC1231N is a miniature normally-closed
(1-Form-B) single-pole solid state relay in a 4-pin
SOP package that employs optically coupled
MOSFET technology to provide 1500Vrms of input to
output isolation. The optically coupled outputs, which
use patented OptoMOS architecture, are controlled
by a highly efficient infrared LED.

Features
• 0.4mm Distance Through Insulation
(Supplementary Isolation Requirement of
EN60950)
• 1500Vrms Input/Output Isolation
• Low Drive Power Requirements
• High Reliability
The device is compliant with supplementary isolation
in accordance with EN/IEC 60950-1.
IXYS Integrated Circuits' state of the art double
molded vertical construction packaging enables the
CPC1231N to be one of the world’s smallest 4-pin
relays, which offers board space savings approaching
20% over the competitor’s larger 4-pin SOP relay.
