If your current choice has a lower Rds than a lesser-spec logic-level FET, it’ll generate less heat even though it’s less “on”. Perhaps one of the wires is corrupt.

Thanks again Wayneh and Sgt for your advice. Maybe you alreadymeasured it but just to datasheeh sure, when your problem aises, have you measured if there is still voltage on the gate or even voltage on your PSU? You might go for something like this one: Is it possible to use two or maybe three IRF to handle more amperage?

OK I try again: Thank you for this very good explanation. But then again, if bought at the right place.

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

I would like to use it to switch car heated seat 12V, 8A. See the reference below:. This actually is used for heatedbed in 3D printers up to A. IRFZ44, and you want to switch somewhat higher voltages i. The irf doesnt need 20 Volt tu turn on.

Like the diagram at the top of the page here. Use a baseresistor of say Ohm. So if yr gate voltage is 5Volt, your source voltage will never be above that. Thanks — You are correct. The datasheet indicates max Vgs 4V but the curve shows that at 5V the mosfet can deliver current way above my requirement. Relay Switch Misbehaving Posted by ebsoares in forum: I am actually using it with octocoupler connected to 12V. But you’re irf1450 with some whopping currents and I don’t have any particular device to recommend.

I am getting almost 7V at the gate so no issues.

And a step irc1405 boost converter to supply the 5. Would like to have a non inverting driver, do you have any recommendation how to solve this, or best IC driver for arduino. Some people however have trouble reading a datasheet or do not know what to look for and in that case foing with TTL level FETs is a safe option.

This is datasueet the gate voltage to turn the device on, its the gate voltage at which it switches fully off less than a few uA of current, typically. Or for a power rectifier?

Sorry, your blog cannot share posts by email. 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 transistor will close.

Is there another device that might be better suited? I had a IRF Mosfet but now i understand why it became very hot. However I advise you against building that yourself as they are rather cheap if you just buy them: Should you however be stuck with a FET like the IRF that really needs a high voltage to switch efficiently then use the following circuit: That means you have to have a 12 Volt driver as in this circuit: Much better to use a cheap Darlington transistor then.

It doesnt look dedicated to a steppermotor though, more to drive a rgular DC motor. The gate V is 7V from a separate supply. How we connect irf mosfethere the problem is ….

Thanks very much for your time. But to be sure i had a question. So the currents you are quoting are with a full supply voltage across the FET for a very short time. At 5V volt on the gate, the IRF will pass something around 4. Setting a temperature irf11405 a comfortable level arduino switches the mosfet on for sec followed by a 50sec off time.

IRF1405 Relay/Switch

Good luck, but dont hesitate to ask again shld you need further advice. Should I try to use a BC for exemple to turn on the Mosfet like 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?

With regard to 9V and 5V input, I presume you mean supply voltage.
