I am actually using it with octocoupler connected to 12V. Keep an eye on the temperature though when you start using it with 8 amps. For example, when used with a high frequency PWM and high amps, careful testing must be done, because high frequency means more time spent in the linear zone, and these parts can quickly get hot and burn, differently of TO parts, that can also burn, but only after some minutes of overheating.

Though that seems like the FET is suitable for an Arduino, I do not think it is an optimal combination. It shows the same behaviour when I use 3. I will try it again after soldering it instead of using a breadboard.
If the steppermotor does not draw too much, think about an ULN Would be interested to hear how the FET holds out on 8 Amps. More and more cheap Mosfets. Thanks — You are correct. That just will make your circuit much easier and save you a transistor and resistor. You may want to read up here https: For the IRF it is even worse. And a step up boost converter to supply the 5.
The only conditions are it should have high switching speed so low rds on and high break down voltage. Thank you for the clear explanation. As the can be fed with up to 18 Volt, it shouldnt be a big problem to use the to switch. Try just to test without the converter, 3.
Looking at those graphs one can see that at a gate to source level of 5V Arduino levels the IRF is only capable of delivering 1 Amp, whereas it is specified for 5,6 Amps continuous current.
I want to put around 10A of current trough a coil to make a partical accelerator. I even used feedback protective diode with motor. How we connect irf mosfethere the problem is ….

Can i use this circuit with Arduino to drive 2 x 20W 1. For a mA current you then need a seriesresistor of 33 Ohm. Or for a power rectifier? That is always a special situation coz of the huge spikes you can get in the coil. I am not sure what voltage you need but you may try this one a 30n This is for direct transfer so it is already mirrorred the right way. An attiny85 could do that as well. If you come up with an idea I would be happy to hear it.
Glad to be able to contribute! The datasheet indicates max Vgs 4V but the curve shows that at 5V the mosfet can deliver current way above my requirement. However it has a very low Rdson. The STP3NA I do not know very well and I couldnt quickly find a readable datasheet, but though it doesnt seem to be a Logic level FET, from what I could see, it should open enough around 3 volt already… but if you have a better datasheet, please check that.
I am not sure if there is an easier way to do it.
Using MOSFETS with TTL levels (5 Volt and Volt) – Arduino, ESP & Raspberry Pi stuff
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. At 5V volt on the gate, the IRF will pass something around 4. But in reality you dont need that formula as it mainly has to do with the range wherein the FET DrainSource acts as a pure resistor. See the reference below: Using the transistor to drive the gate with higher voltage solved the problem.
Backyard controller design Eric’s Arcana and RiderX. At 10 volt it is 4mohm and the fet can take 45 amp, but at 4. This will need a good heatsink if the load is on for more than a second or two, but it is no issue if it gets millisecond pulses every few seconds.
The two P-channel mosfet will be driven by transistors.
Notify me of new comments via email. I should turn on a load some LED lamps in paralel with a Mosfet. Yes im using Arduino to control the circuit. I am not sure where you are based but the IRL costs abt 60 cts where I am. It is not expensive: Is it possible to use two or maybe three IRF to handle more amperage?

I have a hard time believing it would work properly for reasons I explained earlier, but if you say it works for you… great. Every time I tried with new IRF, but any of them worked only for first time. Was that the same as for the mosfet? So the currents you are quoting are with a full supply voltage across the FET for a very short time.
Sorry, your blog cannot share posts by email. The circuit should be robust enough to support the load during a few minutes. Do you have any idea why is the mosfet not working properly and letting the 12v works on the led strip?
