LCA110L is a current-limited, normally open
(1-Form-A) solid state relay that uses optically
coupled MOSFET technology to provide 3750Vrms of
input to output isolation.
Its optically coupled outputs, which use the patented
OptoMOS architecture, are controlled by a highly
efficient infrared LED.
Use the LCA110L to replace mechanical relays,
and gain the superior reliability associated with
semiconductor devices, which, because they have no
moving parts, can offer faster, bounce-free switching
in a more compact surface mount or through-hole
package.

Absolute Maximum Ratings are stress ratings. Stresses in
excess of these ratings can cause permanent damage to
the device. Functional operation of the device at conditions
beyond those indicated in the operational sections of this
data sheet is not implied.
Typical values are characteristic of the device at +25°C,
and are the result of engineering evaluations. They are
provided for information purposes only, and are not part of
the manufacturing testing requirements.

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
LCA110L / LCA110LS MSL 1
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.
Device Classifi cation Temperature (Tc) Dwell Time (tp) Max Refl ow Cycles
LCA110L 250ºC 30 seconds 1
LCA110LS 250ºC 30 seconds 3
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.
