Ordering Information
Pin Configuration
The CPC1972 is an AC Solid State Switch using
optical coupling with dual power silicon controlled
rectifier (SCR) outputs to produce an alternative to
optocoupler and Triac circuits. The CPC1972 switches
are robust enough to provide a blocking voltage
of up to 800VP . In addition, tightly controlled zero
cross circuitry ensures switching of AC loads without
the generation of transients. The input and output
circuits are optically coupled to provide 3750Vrms of
isolation and noise immunity between the control and
load circuits. As a result the CPC1972 is well suited
for industrial environments where electromagnetic
interference could disrupt the operation of
electromechanical relays.

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
CPC1972G / CPC1972GS 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
CPC1972G / CPC1972GS 250ºC 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- or Fluorine-based solvents or fluxes should not be used. Cleaning methods that employ ultrasonic energy
should not be used.
