(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.
