Antonio, thank you for expanding.

IRF Datasheet, PDF – Alldatasheet

They are good switches,but you dont want to dahasheet them as resistors. Should I try to use a BC for exemple to turn on the Mosfet datazheet the schematic 3 and in this case when I put my output high the Mosfet is off, so I should put it Low to turn on my load, is it? Thanks in advance, Ruben. The recommendation was good. Not an ideal choice, but a good one.

That just will make your circuit much easier and save you a transistor and resistor. Realise though datwsheet it is an inverting circuit. For the differences, print out both datasheets and look at each value I am not sure where you are based but the IRL costs abt 60 cts where I am.

The first plot refers to IRF Not sure datasheft what bridge you need. Thanks very much for your time. Sorry, your blog cannot share posts by email. The dissipation then is 5x5x0. What type of step up converter are you using?

Please help me out. What is the difference between the two components? Keep an eye on the temperature though when you start using it with 8 amps. The IRL is a logic level FET and putting 5 Volt on the gate should be enough to open it up, albeit that it has daatsheet drain source resistance of less than one ohm, though that depends a bit on the current and the temperature.

See the reference below:. The battery is ok and gives a steady 4 volts.

Would like to have a non inverting driver, do you have any recommendation how to solve this, or best IC driver for arduino. You need a logic fet for that such as the IRL series.

Do you have any idea why is the mosfet not working properly and letting the 12v works on the led strip? But then again, if bought at the right place. It contains an opto-isolator and does all the gate driving. Perhaps it is a lose wire or something. I would like to use it to switch car heated seat 12V, 8A. Pick this device instead of the other one. 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. It is not a true logic level mosfet, it needs some 10 volts.

But if it is working for you, that is good. You should look at the I-V curves specified irf50 the device. Thanks a lot for this excellent article.

Looking at the curve, at a gate to source voltage of 5V the IRF is hardly turned on. To find out more, including how to control cookies, see here: Was that the same as for the mosfet?

Much better to use a cheap Darlington transistor then. Anyway, depending on your circuit, I am not sure if you need a logic level P fet as often there is transistor driving the mosfet.
