Mosfet Heating Reasons at Donna Hildebrant blog

Mosfet Heating Reasons. The problem that i am encountering is that the mosfet is heating up so much even though the voltage and current applied to the. I found that it only gets hot at low duty cyclex. I'm switching a 12v 500ma resistive load (led strip) with a irf540 mosfet and it's getting very hot when it's on and. Dynamic thermal behavior of mosfets. The irfz44n is driven from a pwm of 244 hz. The simplest definition of rjc is the heat resistance between the junction and the casing. The next thing to say. What might be the possible reasons? Poor heat sinking can destroy the mosfet from excessive temperature. The mos tube current heat is minimal for the following reasons: If there isn't much airflow around the mosfet then a few hundred milliwatts can easily warm it by several tens of °c and probably within a few dozen seconds. Simulation and calculation of high power pulses. At higher duty cycles the mosfet is not heated at all. Generally speaking, a mosfet passing high current will heat up.
