THERMAL RESISTANCE

From junction to case

Rth j-c = 8 K/W

HEATSINK DESIGN EXAMPLE

With derating of 8 K/W, the value of heatsink thermal resistance is calculated as follows:

given RL = 8 Ω and VP = 24 V, the measured maximum dissipation is 4,1 W; then, for a maximum ambient temperature

of 60 °C, the required thermal resistance of the heatsink is:

Rth h-a = -1---5---40---,--1–-----6---0-- – 8 ≈ 14 K/W

Note: The metal tab (heatsink) has the same potential as pin 5 (GND).
