It might not even be very warm at all. The dc curve is a flat line at about 2A till 20V, and falls sharply after that to mA at 40V.

The continuous current is when the mosfet is fully on. Can you please link the datasheet? The IRFZ44N is a hexFET designed for switching applications so using it in linear applications runs a risk of destroying it and you being left scratching your head as to why it went pop.

I have a large heatsink with a fan on it.

IRFZ44 MOSFET. Datasheet pdf. Equivalent

Otherwise, I may have to change it all to a 2N and make a mess. Well, the mosfet died. However, I have tested it a lot at V and 1A. Yes, a MOSFET will go into thermal runaway if the gate-source voltage is below the zero-temperature-coefficient threshold. Nasa document explaining it.

I have built an electronic load. Added on Datashete Andy aka k 10 Ifrz44 EE rocketscientist 62k 2 21 Within about a milli second, a hot spot can develop in the hexfet and a localized temperature of over centigrade results and blows a hole in it before the feedback loop can respond.

Expecting reliability at any more datashete 30W even with excellent cooling is unrealistic.

It is huge difference between 3A 40V and 3A 5V. Any idea what the max current might be at 30V and 40V so as not to cause damage?

Infineon document on thermal instability. It’s made with a pulse to prevent self-heating and the remotest possibility of thermal runaway at lower datasjeet voltages; note how a gate voltage of 4. Post as a guest Name. This is the thermal runaway I refer to. VGS must be greater than 4V to lower Ron.

The electronic load does work badly smoothed 40V DC 3A. This isn’t some theoretical annoyance that doesn’t really happen. Case temp does not go over 40C. Home Questions Tags Users Unanswered. In hindsight, I should have added a couple of resisters upstream of the drain to lower the voltage across the mosfet.

This mosfet will fail at above 2A at all voltages below 20V. This also means the SOA curves in the datasheet are probably not all correct.

I have tested it only for few seconds at this power. I tested today at Indraneel 1, 4 You have to work with power dissipation figures. Extrapolating the points where the mosfet worked and did not work the imaginary DC operation line does not give me a line parallel to the other lines at difference pulse widths.
