CPC1125N is a miniature normally-closed (1-Form-B),
single-pole solid state relay. It uses IXYS Integrated
Circuits' patented, optically coupled, OptoMOS
architecture to provide 1500Vrms of
input/output isolation in a small 4-pin SOP package.
CPC1125N uses IXYS Integrated Circuits' state of
the art double-molded vertical construction packaging
to produce one of the world’s smallest relays. It
is ideal for replacing larger, less-reliable reed and
electromechanical relays.

Manufacturing Information
Moisture Sensitivity
All plastic encapsulated semiconductor packages are susceptible to moisture ingression. IXYS Integrated
Circuits classifies 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) classification 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 Moisture Sensitivity Level (MSL) Classifi cation
CPC1125N MSL 3
ESD Sensitivity
This product is ESD Sensitive, and should be handled according to the industry standard JESD-625.
Soldering Profile
Provided in the table below is the Classification Temperature (TC) of this product and the maximum dwell time the
body temperature of this device may be (TC - 5)ºC or greater. The classification temperature sets the Maximum
Body Temperature allowed for this device during lead-free reflow processes. For through-hole devices, and any other
processes, the guidelines of J-STD-020 must be observed.

Board Wash
IXYS Integrated Circuits recommends the use of no-clean flux formulations. Board washing to reduce or remove flux
residue following the solder reflow process is acceptable provided proper precautions are taken to prevent damage
to the device. These precautions include, but are not limited to: using a low pressure wash and providing a follow
up bake cycle sufficient to remove any moisture trapped within the device due to the washing process. Due to the
variability of the wash parameters used to clean the board, determination of the bake temperature and duration
necessary to remove the moisture trapped within the package is the responsibility of the user (assembler). Cleaning
or drying methods that employ ultrasonic energy may damage the device and should not be used. Additionally, the
device must not be exposed to flux or solvents that are Chlorine- or Fluorine-based.
