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	MAX	UNIT
D-8 PACKAGE
I_S	Safety input, output, or supply current	R_θJA = 94.3°C/W, V_I = 5.5V, T_J = 150°C, T_A = 25°C	241	mA
		R_θJA = 94.3°C/W, V_I = 3.6V, T_J = 150°C, T_A = 25°C	368	mA
		R_θJA = 94.3°C/W, V_I = 2.75V, T_J = 150°C, T_A = 25°C	482	mA
		R_θJA = 94.3°C/W, V_I = 1.89V, T_J = 150°C, T_A = 25°C	701	mA
P_S	Safety input, output, or total power	R_θJA = 94.3°C/W, T_J = 150°C, T_A = 25°C	1325	mW
T_S	Maximum safety temperature		150	°C

(1) The maximum safety temperature, T_S, has the same value as the maximum junction temperature, T_J, specified for the device. The I_S and P_S parameters represent the safety current and safety power respectively. The maximum limits of I_S and P_S must not be exceeded. These limits vary with the ambient temperature, T_A.

The junction-to-air thermal resistance, R_θJA, 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:
T_J = T_A + R_θJA × P, where P is the power dissipated in the device.
T_J(max)= T_S = T_A + R_θJA × P_S, where T_J(max) is the maximum allowed junction temperature.
P_S = I_S × V_I, where V_I is the maximum input voltage.
