Can you explain further about the data sheet as shown below?

Latest Updated:02/01/2007


The data sheet describes derating factor dT (%) for the case temperature as shown in the figure below.
Does this derating factor also apply to the drain current (direct current), or any other parameters?


The derating factor does not apply to the drain current, but as the temperature rises, the internal resistance becomes higher, and as a result, the drain current is affected by the derating factor in the form of power dissipation.
The drain-source voltage is not affected by the derating factor, but usage within 80% of the rating is still advised.
