(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 devices such that T
J
= T
A
. No guarantee of parametric performance is indicated in the electrical tables under
conditions of internal self-heating where T
J
> T
A
.
(2) 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 and are not guaranteed on
shipped production material.
