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) 50°/W when
mounted on a 1in²
pad of 2 oz copper
b) 105°/W when
mounted on a .04 in²
pad of 2 oz copper
c) 125°/W when mounted on a
minimum pad.
