Heat sink calculator
Calculates thermal properties of a power device mounted on a heat sink
Example 1: Must calculate the thermal resistance of a heat sink to keep the junction temperature under 140 degrees celsius at 30 watt power dissipation when using IRFZ44 mosfet in a maximum of 60 degrees ambient temperature | View example |
Example 2: Must calculate the junction temperature of a mosfet at 50 watt dissipation when mounted on to a 0.8°C/W heat sink | View example |
Example 3: Must calculate the maximum power dissipation of a certain transistor mounted on to a 2°C/W heat sink | View example |
You may use one of the following SI prefix after a value: p=pico, n=nano, u=micro, m=milli, k=kilo, M=mega, G=giga
