Works as it should! In hindsight, I should have added a couple of resisters upstream of the drain to lower the voltage across the mosfet.

Working as intended datasheet can be found online, works just as discribed in there Verified purchase: So to answer my own question Figure 1 and figure 2 describe the DC operations despite this measurement being made with a 20 us pulse: Well, the mosfet died.

This one failed with only 2. By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

Any idea what the max current might be at 30V and 40V so as not to cause damage? It is huge difference between 3A 40V and 3A 5V. Ratings and Reviews Write a review.

Email Required, but never shown. 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. Seems to hold up well. This is the thermal runaway Dataseet refer to. This mosfet will fail at above 2A at all voltages below 20V. The continuous current is when the mosfet is fully on.

It works in my project without error, I did have to replace the heatsink even though it was well under specification, but at this price bearing in mind specification assume you have infinite cooling who can complain? I couldn’t find anything at 0Hz linear operation. Andy aka k 10 The electronic load does work badly smoothed 40V DC 3A. 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.

Indraneel 1, 4 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. Damage could be caused by overheat in your case DC load.

So, they too may in reality be curving downwards much more at higher voltages i. Yes, a MOSFET will go into thermal runaway if the gate-source voltage is below the zero-temperature-coefficient threshold. Skip to main content. The lowest-priced brand-new, unused, unopened, undamaged item in its original packaging where packaging is applicable.


You have to work with power dissipation figures. Tony EE rocketscientist 62k 2 21 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. Otherwise, I may have to change it all to a 2N and make a mess. I can vouch for seeing it on a design I was asked to look at.

I have a large heatsink with a fan on it. Expecting reliability at any more than 30W even with excellent cooling is unrealistic.

Nasa document explaining it. So that probably explains the missing dc line in the SOA curve. Sign up using Email and Password. However, I have tested it a lot ifrz44e V and 1A.
