Find a heat sink to keep a TO-220 device below the maximum
150 °C junction temperature in forced convection at 400 ft/min.
Device must be electrically insulated and mounted with a labor
saving clip.
Given:
PD = 12 watts
RθJC = 2.5°C/W (from semiconductor manufacturer)
TJ max = 140°C (from semiconductor manufacturer)
TA max = 50°C
A Hi-Flow pad works great with clip mounting and provides the
necessary electrical insulation. Thermal resistance for
Hi-Flow at low pressure is 1.15°C/W (from page 87).
Using equation 1, solve for RθSA
RθSA = 140 – 50 - (2.5 + 1.15) = 3.85°C/W

Many styles are available. If board space is a concern,
533202B02551G (pg 55) meets the requirements.
According to the above graph, an airflow of 400 ft/min results
in a thermal resistance of 3°C/W. This is less than the required
thermal resistance of 3.85°C/W and is therefore acceptable
under these airflow conditions.
If height is a concern, 533702B02552G would meet the
requirements and is only 1.0” tall
Find a space saving heat sink to keep a TO-220 device below the
maximum 150°C junction temperature in natural convection. Device
will be screw mounted with an electrically conductive interface.
Given:
PD = 6 watts
RθJC = 3°C/W (from semiconductor manufacturer)
TJ max = 150°C (from semiconductor manufacturer)
TA max = 65°C
A KonduxTM pad is a good choice for electrically conductive
applications. Thermal resistance for KonduxTM can be determined
from the following graph.

How To Select a Heat Sink
At 2 in-lb of torque the thermal resistance
is approximately RθCS = 0.5°C/W
Using equation 1, solve for RθSA
RθSA = 150 – 65 - ( 3 + 0.5) = 10.7°C/W

The Index by Heat Sink Style on page 8 lists space saving heat sinks.
Several models are in the 10 °C/W range. Choose the one that best
fits the application and verify thermal resistance from graph.
Part number 593202B03500G shows
a 60 °C temperature rise at 6 watts.
RθSA = 60 = 10.0°C/W

Which meets the above requirement in natural convection.
