R
θJA
is the sum of the junction-to-case and case-to-ambient 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) 50° C/W when
mounted on a 1 in
2
pad of 2 oz. copper.
b) 105° C/W when
mounted on a 0.04 in
2
pad of 2 oz. copper.
c) 125° C/W on a minimum
mounting pad.
