Clare and IXYS have combined to bring OptoMOS®
technology, reliability and compact size to a new
family of High Power Solid State Relays. As part of
this new family, the CPC1777 single pole normally
open (1-Form-A) DC Solid State Relay employs
optically coupled MOSFET technology to provide
2500Vrms of input to output isolation.

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.
Features
• 100% Solid State
• Compact i4-PAC Power Package
• Low Thermal Resistance (0.35°C/W)
• 4.6ADC Load Current with 5°C/W Heat Sink
• Electrically Non-conductive Thermal Pad for Heat
Sink Applications
• Low Drive Power Requirements
• Arc-Free With No Snubbing Circuits
• 2500Vrms Input/Output Isolation
• No EMI/RFI Generation
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 2500Vrms isolation but also
very low thermal resistance (0.35°C/W).
