They indeed can stand almost 7A, but only when sufficiently on or off. The standard mosfet IRF series etc is designed to run from 10V. There are three recommended ones, in order of decreasing cost:.

Is it possible to use two or maybe three IRF to handle more amperage? Excellent post, was very illuminating! A logic level mosfet means that it is designed to turn on fully from the logic level of datashwet microprocessor. That 52 mOhms at 2. Is this what you mean? Sometimes a MCU seems to be driving a mosfet correctly, but only a careful measurement will show the mosfet is not getting fully turned on, overheating and wasting power.

Joe, good idea, but as I picture your changes, the emittor will be at 12 Volt when open, datasheet yr Arduino will set the basis at a max of 5Volt, which would cause the transistor to close again. Switching speed indeed is important. The IRF can obviously take 4 amps, but sadly it expects a higher voltage on its gate than the most microcontrollers can deliver i presume you will use a microcontroller. This site uses cookies.

Then you can find the current in the datasheet? Using the transistor to drive the gate with higher voltage solved the problem. It start switching on at around 3V and it seems to be quite wide open at 4,5V. It shows the same behaviour when I use 3. The dissipation then is 5x5x0. It contains an opto-isolator and does all the gate driving.

Sorry, your blog cannot share posts by email. If it would be just a wire i.

It seems mosfet get burned every time. I am not sure what datasheet you looked at but I do not see a max of 4Volt, I see a max of ca 20 Volt.

Can i use this circuit with Arduino to drive 2 x 20W 1. You might go for something like this one: The relatively cheap BUZ11 is also an option. Thanks for pointing out that series.

Here’s the Yahoo home page: OTC high-current motor drivers are pretty much unaffordable. So no R1 and T1 from your diagram link? Thanks again Wayneh and Sgt for your advice.

IRFZ44, and you want to switch somewhat higher voltages i. Another thing to beware of in datasheets is Vthresh threshhold voltage.

So, mistakes during development can be fatal. Oh i fully agree David. I am not sure where you are based but the IRL costs idf1405 60 cts where I am. Mar 31, 5. I am not sure if there is an easier way to do it.
