(1) Electrical Table 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 T
J
= T
A
. No specification of parametric performance is indicated in the electrical tables under
conditions of internal self heating where T
J
> T
A
. See Note 6 for information on temperature de-rating of this device." Min/Max ratings
are based on product characterization and simulation. Individual parameters are tested as noted.
