Notes:
1: RθJA 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. RθJC is guaranteed by design while RθCA is determined by the user's board design.
a) 50° C/W when
mounted on a 1 in2
pad of 2 oz. copper.
b) 105° C/W when
mounted on a 0.04 in2
pad of 2 oz. copper.
c) 125° C/W on a minimum
mounting pad.
