How is heat flow determined?

The heat generated by a chip flows from the transistor junctions where it is generated through the substrate and package. It can be spread across a heat sink, and then carried away through the air by means of convection. Just as current flow is determined by the voltage difference and electrical resistance, the heat flow is determined by temperature difference and thermal resistance.

How to Calculate Temperature Difference between Transistors?

Temperature Difference between Transistors calculator uses Temperature Difference Transistors = Thermal Resistance between junction and Ambient*Power Consumption of Chip to calculate the Temperature Difference Transistors, The temperature difference between transistors formula is calculated when too much power is dissipated. This makes the transistor junction too hot and the transistor will be destroyed. A typical maximum temperature is between 100°C and 150°C, although some devices can withstand higher maximum junction temperatures. Temperature Difference Transistors is denoted by ΔT symbol.

How to calculate Temperature Difference between Transistors using this online calculator? To use this online calculator for Temperature Difference between Transistors, enter Thermal Resistance between junction and Ambient (Θ_j) & Power Consumption of Chip (P_chip) and hit the calculate button. Here is how the Temperature Difference between Transistors calculation can be explained with given input values -> 2400.896 = 3010*0.000797.
