LAA125 is a 350V, 170mA, 16 dual normally open
(1-Form-A) relay. It combines enhanced peak load
current capability with low on-resistance. Its MOSFET
switches and photovoltaic die provide 3750Vrms of
input to output isolation.
The optically coupled outputs, that use patented
OptoMOS architecture, are controlled by a highly
efficient GaAIAs infrared LED.
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 two switches in a single 8-pin
package.

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) 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
LAA125 / LAA125S / LAA125P 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
LAA125 / LAA125S 250ºC for 30 seconds
LAA125P 260ºC for 30 seconds
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.
