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