(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 ensure of parametric performance is indicated in the electrical tables under
conditions of internal self heating where T
J
> T
A
. See Application Notes for information on temperature de-rating of this device. Min/Max
ratings are based on product testing, characterization and simulation. Individual parameters are tested as noted.
(2) Parameters ensured by electrical testing at 25°C.
(3) Positive Value is current into device.
