TYPICAL CHARACTERISTICS (25 °C, unless otherwise noted)
Current Derating* Power Derating
Note
When mounted on 1" x 1" FR4 with full copper.
* The power dissipation P
D
is based on T
J (max.)
= 150 °C, using junction-to-case thermal resistance, and is more useful in settling
the upper dissipation limit for cases where additional heatsinking is used. It is used to determine the current rating, when this
rating falls below the package limit.
