(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
. Performance is indicated in the electrical tables under conditions of internal self
heating where T
J
> T
A
. See Applications Section 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.
(2) Parameter 100% production tested at 25°C.
