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. Indraneel 1, 4 Infineon document on thermal instability. Andy aka k 10 It is huge difference between 3A 40V and 3A 5V. I have a large heatsink datzsheet a fan on it. Otherwise, I may have to change it all to a 2N and make a mess.

Did you not understand my answer with Temp irgz44 Figure 1 and figure 2 describe the DC operations despite this measurement being made with a 20 us pulse: Well, the mosfet died. Home Questions Tags Users Unanswered.

The dc curve is a flat line at about 2A till 20V, and falls sharply after that to datasheet at 40V. Case temp does not go over 40C. It was not even warm, maybe only at 35C or so.

Post as a guest Name. Nasa document explaining it. So to answer my own question I have tested it only for few seconds at this power.

Added on APR However, I have tested it a lot at V and 1A.

Any idea what the max current might be at 30V and 40V so as not to cause damage? The continuous current is when the mosfet is fully on. 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. The electronic load does datawheet badly smoothed 40V DC 3A.

IRFZ44, SiHFZ44 product information

I tested today at In hindsight, I should have added a couple of resisters upstream of the drain to lower the voltage across the mosfet. On semi document on thermal instability Infineon document on thermal instability Ditto from Fairchild Nasa document explaining it Which figure?

It might not even be very warm at all. At the time I did not understand the SOA curves. Yes, a MOSFET will go into thermal runaway if the gate-source voltage is below the zero-temperature-coefficient threshold.

I couldn’t find anything at 0Hz linear operation. This is the thermal runaway I refer to. 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. VGS must be greater than 4V to lower Ron. I have built an electronic load.

Expecting reliability at any more than 30W even with excellent cooling is unrealistic. So, they too may in reality be curving downwards much more at higher voltages i. You have to work with power dissipation figures.
