LAA110L is a dual normally open (1-Form-A) Solid
State Relay that has two independently controlled,
optically coupled MOSFET switches with an additional
current limiting circuit. The MOSFET switches and
photovoltaic die use Clare’s patented OptoMOS®
architecture to provide 3750Vrms of input to output
isolation. The optically coupled outputs are controlled
by highly efficient GaAIAs infrared LEDs. This dual
switch OptoMOS relay provides a more compact
design solution than discrete single-pole relays in a
variety of applications, and saves board space by
incorporating both switches in a single 8-Pin package.

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
LAA110L / LAA110LS / LAA110PL 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
LAA110L / LAA110LS 250ºC for 30 seconds
LAA110PL 260ºC 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 may be necessary if a wash is used after solder reflow processes. Chlorine-based or Fluorine-based solvents
or fluxes should not be used. Cleaning methods that employ ultrasonic energy should not be used.
