Clare and IXYS have combined to bring OptoMOS

technology, reliability and compact size to a new

family of high power solid state relays. The

CPC1978J, a 1-Form-A solid state relay, is part of

this new family. The CPC1978J employs optically

coupled MOSFET technology to provide 2500V

input to output isolation. The efficient MOSFET

switches and photovoltaic die use Clare’s patented

OptoMOS architecture while the input is controlled

by a highly efficient GaAlAs infrared LED. The

combination of low on resistance and high load

current handling capability makes the relay suitable

for a variety of high performance switching

applications.

The unique i4-PAC™ package pioneered by IXYS

allows solid state relays to achieve the highest

current and power ratings. This package features an

IXYS unique process where the silicon chips are soft

soldered onto the Direct Copper bond (DCB)

substrate instead of the usual copper leadframe. The

DCB ceramic, the same substrate used in high

power modules, not only provides 2500V

but also very low thermal resistance.
