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 CPC1718 single-pole
normally open (1-Form-A) DC Solid State Power
Relay employs optically coupled MOSFET technology
to provide 2500Vrms of input to output isolation.
The output, constructed with an efficient MOSFET
switch 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 DC
switching applications.
The unique ISOPLUS-264 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
2500Vrms isolation but also very low thermal
resistance (0.3 °C/W).
