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, constructed with efficient
MOSFET switches and photovoltaic die, uses 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
enables 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).
