Why should I not give this 5 star? It might not even be very irz44e at all. Otherwise, I may have to change it all to a 2N and make a mess. Skip to main content. So to answer my own question 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.

Ratings and Reviews Write a review. 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?

Added on APR On semi document on thermal instability.

IRFZ44 MOSFET. Datasheet pdf. Equivalent

Chupacabras ratasheet, 2 11 The continuous current is when the mosfet is fully on. Indraneel 1, 4 This isn’t some theoretical annoyance that doesn’t really happen. This mosfet will fail at above 2A at all voltages below 20V. Infineon document on thermal instability.

This also means the SOA curves in the datasheet are probably not all correct. Post as a guest Name. This item doesn’t belong on this page. 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.


Yes, a MOSFET will go into thermal runaway if the gate-source voltage is below the zero-temperature-coefficient threshold. Nasa document explaining it. Show More Show Less.

So, they too may in reality be curving downwards much more at higher voltages i. I have tested it only for few seconds at this power.

This is the thermal runaway I refer to.

I couldn’t find anything at 0Hz linear operation. You have to work with power dissipation figures. See details for additional description.

I can vouch for seeing it on a design I was asked to look at. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Did you not understand my answer with Temp rise?

Email Required, but never shown. The IRFZ44N is a hexFET designed for switching applications so using it in linear irffz44e runs a risk of destroying it and you being left scratching your head as to why it went pop. Save on Transistors Trending price is based on prices over last 90 days. Works as it should! Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the dayasheet in non-retail packaging, such as an unprinted box or plastic bag.


It is huge difference between 3A 40V and 3A 5V. By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policydtaasheet that your continued use of the website is subject to these policies.

See all 25 brand new listings. 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.

IRFZ44E International Rectifier, IRFZ44E Datasheet

I have a large heatsink with a fan on it. Case temp does not go over 40C. Working as intended datasheet can be found online, works just as discribed in there Verified purchase: I have built an electronic load. Good deal on some good Mosfet transistors. Work like they are supposed to.

I tested today at Damage could be caused by overheat in your case DC load. You may also like. Figure 1 and figure 2 describe the DC operations despite this measurement being made with a 20 us pulse: VGS must be greater than 4V to lower Ron.
