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 CPC1786 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.
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).

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.

MANUFACTURING INFORMATION
Soldering
For proper assembly, the component must be
processed in accordance with the current revision
of IPC/JEDEC standard J-STD-020. Failure to
follow the recommended guidelines may cause
permanent damage to the device resulting in impaired
performance and/or a reduced lifetime expectancy.
Washing
Clare does not recommend ultrasonic cleaning or the
use of chlorinated solvents.
