Thermal Resistance in Silicon Controlled Rectifier Formulas

Thermal resistance of SCR is defined as the the ratio of the temperature difference between the two faces of a material to the rate of heat flow per unit area in a SCR. And is denoted by θ. Thermal Resistance is usually measured using the Kelvin per Watt for Thermal Resistance. Note that the value of Thermal Resistance is always negative.
