In my schematic I use an output with a small resistor Ohms in series with the gate of the N Channel Irf5530a STP3NA and my load is in drain like the first schematic showed in this post, but I have no R1 resistor between gate and source, I only have a resistor like R1 in the second schematic. So, the bottom line is: Thanks — You are correct.

That is definitely enough for most applications. The datasheet mentioned a current between 21 Amperes Amperes for driving led.

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 high input capacutance, bu thta does not need to be a huge problem in simple switching also you may consider browsing through this guide. 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.

Learn how your comment data is processed. The driver will have only 2 inputs, allowing off, fw, rev and brake.

As the can be fed with up to 18 Volt, it shouldnt be a big problem to use the to switch. Thanks in advance, Ruben. Also, if you have the gate floating, the state of the mosfet could be undefined. Every time I tried with new IRF, but any of them worked only for first time.

Setting a temperature to a comfortable level arduino switches the mosfet on for sec followed by a 50sec off time. Then you can find the current in the datasheet?

Would like to have a non inverting driver, do you have any recommendation how to solve this, or best IC driver for arduino. Here is the curve for the IRL Thank you for your answer.

Looking datashfet 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. Is there any logic mosfet capable to drive 25 Amperes?

That just will make your circuit much easier and save you a transistor and resistor. Do you have any idea why is the mosfet not working properly and letting the 12v works on irf50a led strip? My hairs are starting to turn gray: IRFZ44, and you want to switch somewhat higher voltages i.

If Vthresh is given as By continuing to use this website, you agree to their use. According to your post and the datasheet, the IRLN should have no problem supplying the current at datashee voltage, right?

At 10 volt it is 4mohm and the fet can take 45 amp, but at 4. Thanks for your contribution. I am getting almost 7V at the gate so no issues. I would like to use it to switch car heated seat 12V, 8A.


I am using this converter: Notify me of new comments via email. They are good switches,but you dont want to use them as resistors.

Using the transistor to drive the gate with higher voltage solved the problem. Fill in your details below or click an icon to log in: 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.

datawheet It seems mosfet get burned every time. Not an ideal choice, but a good one. Somehow Logic P channel mosfetsarent as plentiful. 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 have a hard time believing it would work properly for reasons I explained earlier, but if you say it works for you… great.

Like the diagram at the top of the page here. Im actualy pondering the same question as Legolas. I was not aware of those. Also the and will be more efficient with this circuit. Hello — Great post! Thanks very much for your time.

Hi, really interesting your information!! You may want to read up here https: Oh i fully agree David. It is not ddatasheet I am not sure what voltage you need but you may try this one a 30n The standard mosfet IRF series etc is designed to run from 10V.
