The LOC117 Single Linear Optocoupler features an
infrared LED optically coupled with two photodiodes.
One feedback (input) photodiode is used to generate
a control signal that provides a servomechanism
to the LED drive current, thus compensating
for the LED's nonlinear time and temperature
characteristics. The other (output) photodiode
provides an output signal that is linear with respect
to the servo LED current. The product features
wide bandwidth, high input to output isolation, and
excellent servo linearity.

Manufacturing Information
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) 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.

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 above (TC - 5)ºC. 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 Division 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.
