HEATSINK DESIGN EXAMPLE
The derating of 8 K/W of the encapsulation requires the following external heatsink (for sine-wave drive):
10 W in 2 Ω at VP = 14,4 V
maximum sine-wave dissipation: 5,2 W
Tamb = 60 °C maximum
Rth j-a = Rth j-tab + Rth tab-h + Rth h-a = -1---5---50---,--–-2----6---0-- = 17,3 K/W
Since Rth j-tab + Rth tab-h = 8 K/W, Rth h-a = 17,3 − 8 ≈ 9 K/W.
