7.8 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
SO5 PACKAGE 
IS Safety input, output, or supply current (1) RθJA = 215.9°C/W, VI = 5.5 V, TJ = 135°C, TA = 25°C 90 mA
RθJA = 215.9°C/W, VI = 3.6 V, TJ = 135°C, TA = 25°C 135 mA
RθJA = 215.9°C/W, VI = 2.7 V, TJ = 135°C, TA = 25°C 185 mA
RθJA = 215.9°C/W, VI = 2 V, TJ = 135°C, TA = 25°C 250 mA
PS Safety input, output, or total power (1) RθJA = 215.9°C/W, TJ = 135°C, TA = 25°C 500 mW
TS Maximum safety temperature (1) 135 °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 should 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.
