IXYS Integrated Circuits Division 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 optically coupled outputs, that use patented
OptoMOS architecture, are controlled by a highly
efficient infrared LED. 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
enables 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 junction-to-case thermal resistance
(0.35°C/W).

2.1 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.
2.2 Heat Sink Calculation
Higher load currents are possible by using lower thermal resistance heat sink combinations.

θJC = Thermal Resistance, Junction to Case (°C/W) = 0.35°C/W
θCA = Thermal Resistance of Heat Sink & Thermal Interface Material , Case to Ambient (°C/W)
PD(99) = Maximum power dissipation with case temperature held at 99ºC = 2.86W
* Elevated junction temperature reduces semiconductor lifetime.

4 Manufacturing Information
4.1 Moisture Sensitivity
All plastic encapsulated semiconductor packages are susceptible to moisture ingression. IXYS Integrated
Circuits Division classified all of its plastic encapsulated devices for moisture sensitivity according to the
latest version of the joint industry standard, IPC/JEDEC J-STD-020, in force at the time of product
evaluation. We test all of our products to the maximum conditions set forth in the standard, and guarantee
proper operation of our devices when handled according to the limitations and information in that standard as well as
to any limitations set forth in the information or standards referenced below.
Failure to adhere to the warnings or limitations as established by the listed specifications could result in reduced
product performance, reduction of operable life, and/or reduction of overall reliability.
This product carries a Moisture Sensitivity Level (MSL) rating as shown below, and should be handled according to
the requirements of the latest version of the joint industry standard IPC/JEDEC J-STD-033.
Device

MSL 1
4.2 ESD Sensitivity
This product is ESD Sensitive, and should be handled according to the industry standard
JESD-625.
4.3 Soldering Profile
This product has a maximum body temperature and time rating as shown below. All other guidelines of
J-STD-020 must be observed.
Device
Maximum Temperature x Time

245°C for 30 seconds
NOTE: The exposed surface of the DCB substrate is not to be soldered.
4.4 Board Wash
IXYS Integrated Circuits Division recommends the use of no-clean flux formulations. However, board washing to
remove flux residue is acceptable. Since IXYS Integrated Circuits Division employs the use of silicone coating as an
optical waveguide in many of its optically isolated products, the use of a short drying bake may be necessary if a wash
is used after solder reflow processes. Chlorine-based or Fluorine-based solvents or fluxes should not be used.
Cleaning methods that employ ultrasonic energy should not be used.
