Notes:
1. R
θJA
is the sum of the junction-to-case and case-to-ambient thermal resistance where the case thermal reference is defined as the solder mounting surface of
the drain pins. R
θJC
is guaranteed by design while R
θCA
is determined by the user's board design.
a) 250°C/W when mounted on a
0.02 in

pad of 2 oz. copper.
b) 270°C/W when mounted on a
minimum pad.
