How to calculate thermal resistance of diodes?
The junction-to-ambient thermal resistance, Rth(j-a), of a small-signal diode can be calculated from its power dissipation as follows:
Equation: Rth(j-a) ＝ (Tj Max - Ta） / P Max
The thermal resistance can be calculated from its power dissipation in the technical datasheet of the diodes.
The following is the formula for calculating the thermal resistance from the junction to the ambient.
Equation: Rth(j-a) ＝ (Tj Max - Ta） / P Max
Rth(j-a): Junction-to-ambient thermal resistance
Tj Max: Maximum junction temperature
Ta: Ambient temperature (temperature condition of P Max)
P Max: Maximum power dissipation
