How To Select a Heat Sink How to select a heat sink The basic equation for heat transfer or power dissipation may be stated as follows: HOW TO SELECT A HEAT SINK Where: PD = the power dissipated by the semiconductor device in watts. ΔT = the temperature difference of driving potential which causes the flow of heat. ΣRθ = the sum of the thermal resistances of the heat flow path across which ΔT exists. The above relationship may be stated in the following forms: TC–TA TS–TA TJ–TA PD = PD = PD = RθCS + RθSA RθSA RθJC + RθCS + RθSA Where: TJ = the junction temperature in °C (maximum is usually...

How To Select a Heat Sink Example B 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. 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 = 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...

CONVERTING VOLUME TO VELOCITY EXAMPLE: The output air volume of a fan is given as 80 CFM. The output area is 6 inches by 6 inches or 36 in2 or 25 ft2. To find velocity: 1000 20 Mounting Surface Temp Rise Above Ambient—°C Thermal Resistance From MTG Surface to Ambient—°C/Watt GRAPH A is used to show heat sink performance when used in a natural convection environment (i.e. without forced air). This graph starts in the lower left hand corner with the horizontal axis representing the heat dissipation (watts) and the vertical left hand axis representing the rise in heat sink mounting surface...
