See figure 5, thermal impedance curves.

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 =
RJC
x RDS ( on ) at TJM

See figure 6, maximum drain current graphs.

IDM = 4 X ID1 as calculated in footnote (3).
