PDIS = 0.240 W + 0.731 W + 0.008 W =0.979 W

θJA = 74.57°C/W, TAMB = 45°C

TJ = 45°C + (74.57°C/W) × (0.979 W) = 118.0°C

Here, 150°C is the maximum junction temperature that is

guaranteed before the part breaks down, while 125°C is the

maximum process limit. Because TJ is < 150°C and < 125°C,

this example demonstrates a condition where the part should

perform within process limits.
