IRFZ44, SiHFZ44 product information

In hindsight, I should have added a couple of resisters upstream of the drain to lower the voltage across the mosfet. Expecting reliability at any more than 30W even with excellent cooling is unrealistic. This isn’t some theoretical datssheet that doesn’t really happen. Sign up using Facebook.

It is huge difference between 3A 40V and 3A 5V. Added on APR At the time I did not understand the SOA curves.

On semi document on thermal instability Infineon document on thermal instability Ditto from Fairchild Nasa document explaining it Datazheet figure? Yes, a MOSFET will go into thermal runaway if the gate-source voltage is below the zero-temperature-coefficient threshold. You have to work with power dissipation figures.

This one failed with only 2. Did you not understand my answer with Temp rise? Seems dayasheet hold up well.

So to answer my own question Andy aka k 10 Well, the mosfet died. Email Required, but never shown.

Case temp does not go over 40C. It should probably tolerate a lot if the Vds is limited to only about 10V.

The electronic load does work badly smoothed 40V DC 3A. Chupacabras 3, 2 11 On semi document on thermal instability. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. This mosfet will fail at above 2A at all voltages below 20V. The IRFZ44N is a hexFET designed for switching applications so using it in linear applications runs a risk of destroying it and you being left scratching your head as to why it went pop.

The dc curve is a flat line at about 2A till 20V, and falls sharply after that to mA at 40V. The continuous current is when the mosfet is fully on. Figure 1 and figure 2 describe the DC operations despite this measurement being made with a 20 us pulse: Any idea what the max current might be at 30V and 40V so as not to cause damage?

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. Can you please link the datasheet? I have a large heatsink with a fan on it.

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. I can vouch for seeing it on a design I was asked to look at. I have tested it only for few seconds at this power. So, they too may in reality be curving downwards much more at higher voltages i.

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