Derate linearly 1.2 W/°C for TC > +25°C.

The following formula derives the maximum theoretical ID limit. ID is limited by package and internal wires
and may be limited by pin diameter:
TJM - TC
ID = (
RθJC ) x ( R DS ( on ) at TJM )
(3)
See figure 6, maximum drain current graph.
IDM = 4 X ID1 as calculated in note (2).
