It’s made with a pulse to prevent self-heating and the remotest possibility of thermal runaway at lower gate voltages; note how a gate voltage of 4. Chupacabras 3, 2 11 datwsheet I couldn’t find anything at 0Hz linear operation. Infineon document on thermal instability.

Post dwtasheet a guest Name. Otherwise, I may have to change it all to a 2N and make a mess. Indraneel 1, 4 On semi document on thermal instability. Well, the mosfet died. Yes, a MOSFET will go into datsaheet runaway if the gate-source voltage is below the zero-temperature-coefficient threshold.

Nasa document explaining it. I tested today at This also means the SOA curves in the datasheet are probably not all correct.

I can vouch for seeing it on itfz44 design I was asked to look at. Expecting reliability at any more than 30W even with excellent cooling is unrealistic. The electronic load does work badly smoothed 40V DC 3A. The dc curve is a flat line at about 2A till 20V, and falls sharply after that to mA at 40V.

Figure 1 and figure 2 describe the DC operations despite this measurement being made with a 20 us pulse: Sign up using Facebook. I have a large heatsink with a fan on it.

I have built an electronic load. Damage could be caused by overheat in your case DC load.

So to answer my own question Extrapolating the points where datasheeg 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. This is the thermal runaway I refer to.

Seems to hold up well. Sign up or log in Sign up using Google.

IRFZ44, SiHFZ44 product information

It was not even warm, maybe only at 35C or so. 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 continuous current is when the mosfet is fully on.

At the time I did not understand the SOA curves. It should probably tolerate a lot if the Vds is limited to only about 10V. On semi document on thermal instability Infineon document on thermal instability Ditto from Fairchild Nasa document explaining it Which figure? So, they too may in reality be curving downwards much more at higher datahseet i. Did you not understand my answer with Temp rise? So that probably explains the missing dc line in the SOA curve.

It is huge difference between 3A 40V and 3A 5V.
