Rth j-c
thermal resistance from junction to case
VALUE

The heatsink can be estimated according to application circuit (see Fig.1):
Rth j-a = Rth j-c + Rth c-h + Rth h-a = T----j-(--m-P---a-I-xC--)--(-m–----a-T-x---)a--m----b- = 1----0---5------°1---C-.-8---–--W---6---5------°---C-- = 22.2 K/W .
A heatsink is needed at Rth j-c < 10 K/W and Rth c-h = 0.5 K/W (using silicon grease) with
Rth h-a = 22.2 K/W − (10 + 0.5) K/W = 11.7 K/W.
