transient has not passed, current will again flow up to
the value allowed by the dynamic DC current limiting
of the switches and heating will resume, reactivating
the thermal shutdown mechanism. This cycle of
entering and exiting the thermal shutdown mode will
continue as long as the fault condition persists. If the
magnitude of the fault condition is great enough, the
external secondary protector will activate shunting the
fault current to ground.
2.11 External Protection Elements
The CPC7695 requires only over voltage secondary
protection on the loop side of the device. The
integrated protection feature described above negates
the need for additional external protection on the SLIC
side. The secondary protector must limit voltage
transients to levels that do not exceed the breakdown
voltage or input-output isolation barrier of the
CPC7695. A foldback or crowbar type protector is
recommended to minimize stresses on the CPC7695.

secondary protectors, fused resistors and PTCs.

3. Manufacturing Information
3.1 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.
3.2 ESD Sensitivity
This product is ESD Sensitive, and should be handled according to the industry standard JESD-625.
3.3 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.
3.4 Board Wash
IXYS Integrated Circuits Division recommends the use of no-clean flux formulations. However, board washing to
remove flux residue is acceptable, and the use of a short drying bake may be necessary. Chlorine-based or
Fluorine-based solvents or fluxes should not be used. Cleaning methods that employ ultrasonic energy should not be
used.
