Switching Characteristics
of Normally Open Devices
The TS120 integrated circuit device combines a 350V
normally open (1-Form-A) relay with a Darlington
transistor optocoupler in a single package. The relay
uses optically coupled MOSFET technology to
provide 3750Vrms of input to output isolation. The
efficient MOSFET switches and photovoltaic die use
Clare’s patented OptoMOS® architecture, while the
optically coupled output is controlled by highly
efficient GaAIAs infrared LEDs.
The TS120 enables telecom circuit designers to
combine two discrete functions in a single component
that uses less space than traditional discrete
component solutions.

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
TS120 / TS120P / TS120S 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
TS120 / TS120S 250ºC for 30 seconds
TS120P 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 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.
