If Vthresh is given as So, the bottom line is: 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. 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.

In general you want a MOSFET that has a low Rdson and switches fast at the available triggervoltage 5volt with ttl and ofcourse can take the voltage and current it will be exposed to.

Every time I tried with new IRF, but any of them worked only for first time. I am not sure what voltage you need but you may try this one a 30n The is somewhat better: Say that is 2 Volt. I should turn on a load some LED lamps in paralel with a Mosfet.


I am getting almost 7V at the gate so no issues. The two P-channel mosfet will be driven by transistors. If you feed it with 15Volt the output voltage is around volt which will do the job.

Thanks, I learnt few things in my new journey. I have done like you said.

So the currents you are quoting are with a full supply voltage across the FET for a very short time. The input capacitance is best chosen as low as possible.

If the steppermotor does not draw too much, think about an ULN To find out more, including how to control cookies, see here: Not an ideal choice, but a good one.

That is not surprising. However it has a very low Rdson.

They indeed can stand almost 7A, but only when sufficiently on or off. The simplest circuit is just a 12 V regulator but that is very inefficient. Thanks for pointing out that dstasheet. Well what an amazing article. Or for a power rectifier?

Using MOSFETS with TTL levels (5 Volt and 3.3 Volt)

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. Joe, good idea, but as I picture your changes, the emittor will be at 12 Volt when open, while yr Arduino will set the basis at a max of 5Volt, which would cause the transistor to close again. Use a baseresistor of say Ohm. Great, that is good to know. I bought it and it works with Arduino. Somehow Logic P channel mosfetsarent as plentiful. It already switches on at much lower voltages, albeit not completely, but the optimal voltage is around Volt.

Sadly though it can only dissipate some 80 Watts There is the MTB60N05HD L that does 60 amps 50 Volt and Amps beware of the somewhat ddatasheet input capacutance, bu thta does not dtasheet to be a huge datashet in simple switching also you may consider browsing through this guide. I have a hard time believing it would work properly for reasons I explained earlier, but if you say it works for you… great. According to your post and the datasheet, the IRLN should have no problem supplying the current at this voltage, right?

Hi, really interesting your information!! Thanks very much for your time. I have chosen to put one in just to be sure. It doesnt look dedicated to a steppermotor though, more to drive a rgular DC motor.
