technology, reliability and compact size to a new

family of High Power Solid State Relays. As part of

this new family, the CPC1786 single pole normally

open (1-Form-A) DC Solid State Relay employs

optically coupled MOSFET technology to provide

2500V

The output is constructed with an efficient MOSFET

switch and photovoltaic die that uses Clare’s patented

OptoMOS architecture while the input GaAlAs

infrared LED provides the optically coupled control.

The combination of low on-resistance and high load

current handling capability makes this relay suitable

for a variety of high-performance DC switching

applications.

The unique i4-PAC package pioneered by IXYS

allows solid state relays to achieve the highest load

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

very low thermal resistance (0.35°C/W).
