Keep an eye on the temperature though when you start using it with 8 amps. For a mA current you then need a seriesresistor of 33 Ohm.
Using MOSFETS with TTL levels (5 Volt and 3.3 Volt)
So if yr gate voltage is 5Volt, your source voltage will never be above that. I am not sure if there is an easier way to do it. R1 irv520 just there to limit the current through the gat, coming from a microcontroller pin. Do you have the break out board in the drain or the source?
Should you however be stuck with a FET like the IRF that really needs a high voltage to switch efficiently then use the irf50 circuit: Like the diagram at the top of the page here. More and more cheap Mosfets. Email Required, but never shown. Switching speed indeed is important.
Though that seems like the FET is suitable for an Arduino, I do not think it is an optimal combination. Would be interested to hear how the FET holds out on 8 Amps. Thank you for the clear explanation. If you feed it with 15Volt the output voltage is around volt which will do the job. The is somewhat better: Good luck, but dont hesitate to ask again shld you need further advice. Thanks in advance, Datzsheet. Post was not sent – check your email addresses!
Indeed, more and more FETs availablefor 3. I presume you are aware of the designcriteria of an H-bridge and the chances of shorting your PSU if you dont do the switching correctly. 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. I just need to switch on and off small DC motor. At 5 Volt GS it can however only take some rif520. It doesnt look dedicated to a steppermotor though, more to drive a rgular DC motor. So, the bottom line is: You need a logic fet for that such as the IRL series.
Was that the same as for the mosfet? They are good switches,but you dont want to use them as resistors.
The question is the one joe provided a solution to in an earlier question, except just as you pointed out, his solution doesnt work because the emitter voltage will be close to 12V and the base voltage from the arduino will be 5V so the dataheet will close. Glad to be able to contribute!

Do you have any idea why is the mosfet not working properly and letting the 12v works on the led strip? Maybe you alreadymeasured idf520 but just to make sure, when your problem aises, have you measured if there is still voltage on the gate or even voltage on your PSU? I seem to have missed your reply at first since I did not subscribe to your posts fast enough apparently: According to your post and the datasheet, the IRLN should have no problem supplying the current at this voltage, right?
My hairs are starting to turn gray:
