Notes:
1.
 R
JA 
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
θ
JC 
is guaranteed by design while R
θ
CA 
is determined by the user's board design.
a) R
θ
JA 
is 125
°
C/W (steady state) when mounted on a 1 inch2 copper pad on FR-4.
b) R
θ
JA 
is 208
°
C/W (steady state) when mounted on a minimum copper pad on FR-4.
