Heat sink temperature calculator calculates junction temperature and power



App description

Heat sink temperature calculator

Enter the value and click Calculate. The result will be displayed.

Input data:

Ambient temperature Ta max, unit: C

Junction temperature Tj max, unit: C

Resistance (thermal resistance) R, unit: C/Watt

Resistance Ra, unit: C/Watt

Resistance Rb, unit: C/Watt

Output data: junction temperature, unit: C; power, unit; Watt, BTU / Hour

Usage example

Ambient temperature Ta max: 28C

Junction temperature Tj max: 18C

Resistance (thermal resistance) R: 20C/Watt

Resistance Ra: 30C/Watt

Resistance Rb: 60C/Watt

Click "Calculate" output data at junction temperature: junction temperature: 28C
