The CPC1302 is a dual optocoupler with two
identical, independent channels, each having a
unidirectional input and a high-voltage Darlington
output. Light output from the highly efficient GaAlAs
infrared LED activates its associated, optically
coupled silicon NPN photo-Darlington output
transistor. The input LED and the output transistor are
separated by a 3750Vrms isolation barrier.
With a LED current of only 1mA, a current transfer
ratio of 1000% to 8000% is guaranteed at the
collector of the 350V Darlington output transistor.
The CPC1302's low input current capability with
high current transfer ratios, output voltage capability,
and isolation barrier rating make it ideal for many
applications such as telecom, industrial, and power
control.

Manufacturing Information
Moisture Sensitivity
All plastic encapsulated semiconductor packages are susceptible to moisture ingression. Clare 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 Moisture Sensitivity Level (MSL) Rating
CPC1302G / CPC1302GS MSL 1
ESD Sensitivity
This product is ESD Sensitive, and should be handled according to the industry standard JESD-625.
Reflow 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
CPC1302G / CPC1302GS 250ºC for 30 seconds
Board Wash
Clare recommends the use of no-clean flux formulations. However, board washing to remove flux residue is
acceptable. Since Clare employs the use of silicone coating as an optical waveguide in many of its optically isolated
products, the use of a short drying bake could be necessary if a wash is used after solder reflow processes.
Chlorine- or Fluorine-based solvents or fluxes should not be used. Cleaning methods that employ ultrasonic energy
should not be used.
