You need a logic fet for that such as the IRL series. I have a hard time believing it would work properly for reasons I explained earlier, but if you say it dtasheet for you… great. They are good switches,but you dont want to use them as resistors. Like the diagram at the top of the page here. The 20 Volt you probably saw in the datasheet, but that is the max voltage on the gate.
Email required Address never made public. Do you have any idea why is the mosfet not working properly and letting the 12v works on the led strip? Sorry, your blog cannot share posts by email. Also, if you have the gate floating, the state of the mosfet could be undefined.

Please bear in mind that eventhough a logic level FET, the IRLN is not at its lowest resistance at 5 Volt, but it shld be low enough to make 10 amp no problem. It already switches on at much lower voltages, albeit not completely, but the optimal voltage is around Volt. Not sure though what bridge you need. That is not surprising.
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.
Would be interested to hear how the FET holds out on 8 Dataxheet. R1 is just there to limit the current through the gat, coming from a microcontroller pin. What type of step up converter are you using?
The datasheet indicates max Vgs 4V but the curve shows that at 5V the mosfet can deliver current way above my requirement Thank you for your help. So, mistakes during development can be fatal. Thanks very much for your time. Try just to test without the converter, 3.

This actually is used for heatedbed in 3D printers up to A. How we connect irf mosfethere the problem is …. Then you can find the current in the datasheet?
Good luck with your project. You could consider the FQP27P I was not aware of those. I will try it again after soldering it instead of using a breadboard. I had a IRF Mosfet but now i understand why it became very hot. Fill in your details below or click an icon to log in: It is not expensive: Rds 38mOhm with a Vgs of 3. datashwet

They indeed can stand almost 7A, but only when sufficiently on or off. If you feed it with 15Volt the output voltage is around volt which will do the job.
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. Oh i fully agree David. That means you have to have a 12 Volt driver as in this circuit: The datasheet mentioned a current between 21 Amperes Amperes for driving led. And a step up boost converter irv530a supply the 5. Keep an eye on the temperature though when you start using it with 8 amps. 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.
