Did you not understand my answer with Temp rise? This one failed with only 2. Sign up using Facebook.

Vishay – IRFZ44, SiHFZ44 – Power MOSFET

At the time I did not understand the SOA curves. The dc curve is a flat line at about 2A till 20V, and falls sharply after datsheet to mA at 40V.

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.

On semi document on thermal instability Infineon document on thermal iefz44 Ditto from Fairchild Nasa document explaining it Which figure? Case temp does not go over 40C. This mosfet will fail at above 2A at all voltages below 20V. Sign up using Email and Password. The continuous current is when the mosfet is fully on.

Tony EE rocketscientist 62k 2 21 So, they too may in reality be curving downwards much more at higher voltages i. This also means the SOA curves in the datasheet are probably not all correct. So to answer my own question VGS must be greater than 4V to lower Ron.

IRFZ44, SiHFZ44 product information

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. So that probably explains the missing dc line in the SOA curve. Damage could be caused by overheat in your case DC load.

It should probably tolerate a lot if the Vds is limited to only about 10V.

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. I have built an electronic load. Post as a guest Name. On semi document on thermal instability. Sign up or log in Sign up using Google. Added on APR In hindsight, I should have added a couple of resisters upstream of the drain to lower the voltage across the mosfet.

I have tested it only for few seconds at this power. It is huge difference between 3A 40V and 3A 5V. You have to work with power dissipation figures.

Yes, a MOSFET will go into thermal runaway if the gate-source voltage is below the zero-temperature-coefficient threshold. I tested today at Email Required, but never shown. It was not even warm, maybe only at 35C or so. However, I have tested it a lot at V and 1A. Well, the mosfet died.

Can you please link the datasheet? Andy aka k 10 The electronic load does work badly smoothed 40V DC 3A. I have a large heatsink with a fan on it.
