Home Questions Tags Users Unanswered. Dstasheet as a guest Name. It should probably tolerate a lot if the Vds is limited to only about 10V. This also means the SOA curves in the datasheet are probably not all correct.

This one failed with only 2. This isn’t some theoretical annoyance that doesn’t really happen. I tested today at Datashert to answer my own question Can you please link the datasheet?

The electronic load does work badly smoothed 40V DC 3A. It was not even warm, maybe only at 35C or so.

Email Required, but never shown. So that probably explains the missing dc line in the SOA curve. 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.

Tony EE rocketscientist 62k 2 21 Added on APR VGS must be greater than 4V to lower Ron. Did you not understand my answer with Temp rise?

IRFZ44, SiHFZ44 product information

This mosfet will fail at above 2A at all voltages below 20V. Sign up or log in Sign up using Google. In hindsight, I should have added a couple of resisters upstream of the drain to lower the voltage across the mosfet. Chupacabras 3, 2 11 Figure 1 and figure 2 describe the DC operations despite this measurement being made with a 20 us pulse: Igfz44 Your Answer Discard 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.

It is huge difference between 3A 40V and 3A 5V. Well, the mosfet died.

Damage could be caused by overheat in your case DC load. I can vouch for seeing it on a design I was asked to look at.

Any idea what the max current might be at 30V and 40V so as not to cause damage? The continuous current is when irrz44 mosfet is fully datasheeh. It might not even be very warm at all. Expecting reliability at any more than 30W even with excellent cooling is unrealistic.

Vishay – IRFZ44, SiHFZ44 – Power MOSFET

The dc curve is a flat line at about 2A till 20V, and falls sharply after that to mA at 40V. I have tested it only for few seconds at this power. I have a large heatsink with a fan on it. However, I have tested it a lot vatasheet V and 1A. Nasa document explaining it.

Case temp does not go over 40C. Seems to hold up well.

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. On semi document on thermal instability. You have to work with power dissipation figures.

On semi document on thermal instability Infineon document on thermal instability Ditto from Fairchild Nasa document explaining it Which figure? This is the thermal runaway I refer to.

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