normally open (1-Form-A) Solid State Power Relay is
rated for up to 13A
rms
continuous load current with a
5ºC/W heat sink.
The CPC1918 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 ISOPLUS-264 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 (0.3 °C/W).

Thermal Management
Device high current characterization was performed using Kunze heat sink KU 1-159, phase change thermal
interface material KU-ALC 5, and transistor clip KU 4-499/1. This combination provided an approximate
junction-to-ambient thermal resistance of 12.5°C/W.
Heat Sink Calculation
Higher load currents are possible by using lower thermal resistance heat sink combinations.
