JC is junction-to-case, CH is case-to-heat sink

(2)

RθCH is an important consideration. Assume a 2-mil thickness of thermal grease with a thermal conductivity of 2.5 W/mK between the

pad area and the heat sink and both channels active. The RθCH with this condition is 1.1°C/W for the PHD package and 0.44°C/W for

the DKD package.
