Power dissipation calculator
Calculates the power dissipation of a component package in free air and without any heat sinking material. The result is an estimation based on typical thermal values of components.
|Example 1: Must calculate the junction temperature of the semiconductor packaged in PDIP40 case dissipating 800mW of power in 25 degrees ambient temperature||View example|
|Example 2: Must calculate the maximum ambient temperature of the semiconductor packaged in TO-220 case having a maximum junction temperature of 150 degrees celsius and is dissipating 1.6 watts of power||View example|
|Example 3: Must calculate the maximum power dissipation of the semiconductor packaged in SOT-23 case having a maximum junction temperature of 150 degrees celsius and is required to operate in 60 degrees ambient temperature||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
|J-A thermal resistance||450 °C/W|
|Power dissipation||200 milliwatts|
