WebOct 6, 2024 · As can be seen, the MOSFET thermal response is similar to an RC network electrical response. Its thermal resistance varies depending on the kind of pulse delivered (single-shot or repeated PWM pulses with varying duty cycles), and for pulses longer than 10 ms, the curves begin to plateau and flatten after 100 ms, as seen in the graph. WebThermal Resistance (R) is a measure of resistance to heat flow through a given thickness of material (related directly to the R-value ). Thermal resistance is determined by taking the thickness of a sample and dividing it by its thermal conductivity. Thermal resistivity is the inverse of the thermal conductivity.
