(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 beexceed-

ed.These limits vary with the ambient temperature, TA.
