IRFZ44 MOSFET. Datasheet pdf. Equivalent

You have to work with power dissipation figures. Chupacabras 3, 2 11 Email Required, but never shown.

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

Seems to hold up well.

Home Questions Tags Users Unanswered. This mosfet will fail at above 2A at all voltages below 20V. Andy aka k 10 The dc curve is a flat line at about 2A till 20V, and falls sharply after that to mA at 40V. It might not even be very warm at all. This isn’t some theoretical annoyance that doesn’t really happen. On semi document on thermal instability Infineon document on thermal instability Ditto from Fairchild Nasa document explaining it Which figure? Added on APR So to answer my own question 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. I couldn’t find anything at 0Hz linear operation.

Post as a guest Name. Tony EE rocketscientist 62k 2 21 Did you not understand my answer with Temp rise? Well, the mosfet died. I can vouch for seeing it on a design I was asked to look at.

I have built an electronic load. 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.

VGS must be greater than 4V to lower Ron. So that probably explains the missing dc line in the SOA curve. Sign up using Email and Password.

This is the thermal runaway I refer to. I tested today at Datasheef using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. Expecting reliability at any more than 30W even with excellent cooling is unrealistic.
