http://www.learningaboutelectronics.com/Articles/Diode-resistance.php WebThermal resistance defines the resistance that a heat flow encounters when transferring from one structure (for example: IC junction) to another (for example: ambient air). It is expressed in terms of temperature difference per unit heat flow (units of o C/W). The symbol θ is generally used to denote thermal resistance.
