TYPICAL CHARACTERISTICS (25 °C, unless otherwise noted)

* The power dissipation PD is based on TJ(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.
