on-resistance and high current handling capability. It
uses optically coupled MOSFET technology to provide
3750V
rms
of input to output isolation.
Its optically coupled outputs, which use the patented
OptoMOS architecture, are controlled by a highly
efficient GaAIAs infrared LED.
The LCA710 can be used to replace mechanical
relays, and offers the superior reliability associated
with semiconductor devices. Because it has no moving
parts, it can offer faster, bounce-free switching in a
more compact surface mount or thru-hole package.

Manufacturing Information
Moisture Sensitivity
LCA710
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.

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.

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 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.
