Seems to hold up well.

I have a large heatsink with a irgz44 on it. Infineon document on thermal instability. So that probably explains the missing dc line in the SOA curve.

Did you not understand my answer with Temp rise? I can vouch for seeing it on a design I was asked to look at. This is the thermal runaway I refer to.

Yes, a MOSFET will go into thermal runaway datassheet the gate-source voltage is below the zero-temperature-coefficient threshold. 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.

I couldn’t find anything at 0Hz linear operation. The IRFZ44N is a hexFET designed for switching applications dataxheet using it in linear applications runs a risk of destroying it and you being left scratching your head as to why it went pop.

At the time I did not understand the SOA curves.

So to answer my own question Andy aka k 10 It should probably tolerate a lot if the Vds is limited to only about 10V.

It was not even warm, maybe only at 35C or so. This also means the SOA curves in the datasheet are probably not all correct.

IRFZ44, SiHFZ44 product information

Indraneel 1, 4 In hindsight, I should have added a couple of resisters upstream of the drain to lower the voltage across the mosfet. I have tested it only for few seconds at this power. I tested today at Figure 1 and figure 2 describe the DC operations despite this measurement being made with a 20 us pulse: It is huge difference between 3A datasheey and 3A 5V. This mosfet will fail at above 2A at all voltages below 20V. Home Questions Tags Users Unanswered.

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.

Otherwise, I may have to change it all to a 2N and make a mess. Sign up using Facebook. The continuous current is when the mosfet is fully on. I have built an electronic load. However, I have tested it a lot dqtasheet V and 1A. Post as a guest Name.

Chupacabras 3, 2 11 Any idea what the max current might be at 30V and 40V so as not to cause damage? The electronic load does work badly smoothed 40V DC 3A. So, they too may in reality be curving downwards much more at higher voltages i. This isn’t some theoretical annoyance that doesn’t really happen.
