(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
. Parametric performance is indicated in the electrical tables under conditions of
internal self heating where T
J
> T
A
. See Applications Information 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) Limits are 100% production tested at 25°C. Limits over the operating temperature range are through correlations using the Statistical
Quality Control (SQC) method.
(3) Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary
over time and will also depend on the application and configuration. The typical values are not tested on shipped production material.
(4) Parameter 100% production tested at 25° C.
