Description
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 family, the CPC1908 single pole
normally open (1-Form-A) Solid State Power Relay is
rated for up to 8.5A
rms
continuous load current with a
5°C/W heat sink.
The CPC1908 employs optically coupled MOSFET
technology to provide 2500V
rms
of input to output
isolation. The output is constructed with efficient
MOSFET switches and photovoltaic die that use
Clare’s patented OptoMOS architecture while the
input, a highly efficient 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 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
a unique IXYS process where the silicon chips are
soft soldered onto the Direct Copper Bond (DCB)
substrate instead of the traditional copper leadframe.
The DCB ceramic, the same substrate used in high
power modules, not only provides 2500V
rms
isolation
but also very low thermal resistance (0.35 °C/W).
