6.8 Safety Limiting Values

Safety limiting(1) intends to minimize potential damage to the isolation barrier upon failure of input or output circuitry.
PARAMETER TEST CONDITIONS MIN TYP MAX UNIT
D-8 PACKAGE
IS Safety input, output, or supply current RθJA = 94.3°C/W, VI = 5.5V, TJ = 150°C, TA = 25°C 241 mA
RθJA = 94.3°C/W, VI = 3.6V, TJ = 150°C, TA = 25°C 368 mA
RθJA = 94.3°C/W, VI = 2.75V, TJ = 150°C, TA = 25°C 482
RθJA = 94.3°C/W, VI = 1.89V, TJ = 150°C, TA = 25°C 701 mA
PS Safety input, output, or total power RθJA = 94.3°C/W, TJ = 150°C, TA = 25°C 1325 mW
TS Maximum safety temperature 150 °C
(1) The maximum safety temperature, TS, has the same value as the maximum junction temperature, TJ, specified for the device. The IS and PS parameters represent the safety current and safety power respectively. The maximum limits of IS and PS must not be exceeded. These limits vary with the ambient temperature, TA. 

The junction-to-air thermal resistance, RθJA, in the table is that of a device installed on a high-K test board for leaded surface-mount packages. Use these equations to calculate the value for each parameter:
TJ = TA + RθJA × P, where P is the power dissipated in the device.
TJ(max) = TS = TA + RθJA × PS, where TJ(max) is the maximum allowed junction temperature.
PS = IS × VI, where VI is the maximum input voltage.
