Electrical Characteristics values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in

very limited self-heating of the device such that TJ = TA. No guarantee of parametric performance is indicated in the electrical tables

under conditions of internal self-heating where TJ TA. Absolute Maximum Ratings indicate junction temperature limits beyond which the

device may be permanently degraded, either mechanically or electrically.
