MIL-PRF-19500/555L
1.3 Maximum ratings. Continued.
(1) Derate linearly 0.16 W/°C for TC > +25°C for "non-U" suffix versions, 0.11 W/°C for TC > +25°C for "U" suffix
versions.
(2) See figure 8, thermal impedance curves.
(3) The following formula derives the maximum theoretical ID limit. ID is also limited by package and internal wires
and may be limited due to pin diameter.
TJ (max)-TC
ID=
RθJC x( RDS (on) atTJ (max))
(4) See figure 9, maximum drain current graph.
(5) IDM = 4 ID1; ID1 as calculated in footnote (3).
1.4 Unless otherwise specified, primary electrical characteristics at TC = +25°C.
