IEC SAFETY LIMITING VALUES
safety limiting intends to prevent potential damage to the isolation barrier upon failure of input or output circuitry. A failure of
the IO can allow low resistance to ground or the supply and, without current limiting dissipate sufficient power to overheat the
die and damage the isolation barrier potentially leading to secondary system failures.

Maximum case temperature 150 °C
The safety-limiting constraint is the absolute maximum junction temperature specified in the absolute maximum
ratings table. The power dissipation and junction-to-air thermal impedance of the device installed in the
application hardware determines the junction temperature. The assured junction-to-air thermal resistance in the
Thermal Characteristics table is that of a device installed on a High-K Test Board for Leaded Surface Mount
Packages. The power is the recommended maximum input voltage times the current. The junction temperature is
then the ambient temperature plus the power times the junction-to-air thermal resistance.
