Its optically coupled outputs, which use the patented
OptoMOS architecture, are controlled by a highly
efficient infrared LED.
Designed to replace electromechanical relays, the
PLA170 offers the superior reliability associated
with solid state devices, and provides bounce-free
switching in a more compact surface mount or
thru-hole package.

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.

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 IPC/JEDEC J-STD-020 Classification Temperature (TC) and the maximum total dwell
time (tP) in all reflow processes that the body temperature of these surface mount devices may be (TC - 5)°C or greater.
The device’s body temperature must not exceed the Classification Temperature at any time during reflow soldering
processes.

For through-hole devices, the maximum pin temperature and maximum dwell time through all solder waves is
provided in the table below. Dwell time is the interval beginning when the pins are initially immersed into the solder
wave until they exit the solder wave. For multiple waves, the dwell time is from entering the first wave until exiting the
last wave. During this time, pin temperatures must not exceed the maximum temperature given in the table below.
Body temperature of the device must not exceed the limit shown in the table below at any time during the soldering
process.

*Total cumulative duration of all waves.
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 halide flux or solvents.
