I couldn’t find anything at 0Hz linear operation. Tony EE rocketscientist 62k 2 21 Sign up using Email and Password. Andy aka k 10 At the time I did not understand the SOA curves.

I tested today at It’s made with a pulse to prevent self-heating and the remotest possibility of thermal runaway at lower gate voltages; note catasheet a gate voltage of 4. Home Questions Tags Users Unanswered.

IRFZ44, SiHFZ44 product information

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

The dc curve is a flat line at about 2A till 20V, and falls sharply after that to mA at 40V. The electronic load does work badly smoothed 40V DC 3A. It is huge difference between 3A 40V and 3A 5V. However, I have tested it a lot at V and 1A. 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. Can you please link the datasheet? Did you not understand my answer with Temp rise?

This mosfet will fail at above 2A at all voltages below 20V. Sign datwsheet or log in Sign up using Google. 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 have built an electronic load. You have to work with power dissipation figures. Case temp does not go over 40C. It might not even be very warm at all. datqsheet

This isn’t some theoretical annoyance that doesn’t really happen. Damage could be caused by overheat in your case DC load. Indraneel 1, 4 Any idea what the max current might be at 30V and 40V so as not to cause damage?

Seems to hold up well. Extrapolating the points where the mosfet worked and did lrfz44 work the imaginary DC operation line does not give me a line parallel to the other lines daatasheet difference pulse widths.

It should probably tolerate a lot if the Vds is limited to only about 10V. Nasa document explaining it. This irfz4 the thermal runaway I refer to. So that probably explains the missing dc line in the SOA curve.

VGS must be greater than 4V to lower Ron.
