It was not even warm, maybe only at 35C or so. 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. Save on Transistors Trending price is based on prices over last 90 days. Work like they are supposed to. You may also like. This is the thermal runaway I refer to.

Case temp does not go over 40C. The continuous current is when the mosfet is fully on.


I have built an electronic load.

Good deal on some good Mosfet transistors. Show More Show Less. Email Required, but never shown. Good Work like they are supposed to.

Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer datawheet non-retail packaging, such as an unprinted box or plastic bag. Working as intended datasheet can be found online, works just as discribed in there Verified purchase: Nasa document explaining it. So to answer my own question 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.

It should probably tolerate a lot if the Vds is limited to only about 10V. Did you not understand my answer with Temp rise? This one failed with only 2. Well, the mosfet died. This isn’t some theoretical annoyance that doesn’t really happen. I can vouch for seeing it on a design I was asked to look at.


The lowest-priced brand-new, unused, unopened, undamaged item in its original packaging where packaging is applicable. This mosfet will fail at above 2A at all voltages below 20V.

Chupacabras 3, 2 11 However, I have tested it a lot at V and 1A. 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?

Any idea what the max current might be at 30V and 40V so as not to cause damage?
