TYPICAL CHARACTERISTICS (25 °C, unless otherwise noted)
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-ambient 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.
