THERMAL RESISTANCE
HEATSINK DESIGN EXAMPLE
With derating of 6 K/W, the value of heatsink thermal resistance is calculated as follows:
given R
L
= 8
and V
P
=
±
12 V, the measured maximum dissipation is 7,8 W; then, for a maximum ambient temperature
of 60
°
C, the required thermal resistance of the heatsink is
Note: The metal tab (heatsink) has the same potential as pin 5 (
V
P
).
