IRFA Datasheet(PDF) – Fairchild Semiconductor

However I advise you against building that yourself as they are rather cheap if you just buy them: R1 is just there to limit the current through the gat, coming from a microcontroller pin. It start switching on at around 3V and it seems to be quite wide open at 4,5V.

Checking the datasheet is always a good suggestion. Use a baseresistor of datasheeet Ohm. I am not sure if there is an easier way to do it.

Every time I tried with new IRF, but any of them worked urf530a for first time. It seems mosfet get burned every time. The question is the one joe provided a solution to in an earlier question, except just as you pointed out, his satasheet doesnt work because the emitter voltage will be close to 12V and the base voltage from the arduino will ddatasheet 5V so the transistor will close.

Thanks Adriaan, Though technically it is a voltage divider, that is not really the function of it. Perhaps it is a lose wire or something.

Yes you can make it Ohm. That indeed is odd and I start to wonder if it is the IRL that is shutting down or something else. And as i understand when you put 5 volt on the gate, the output on the source i presume is only 5Volt. 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.

Email required Address never made public. The Vce in saturation is about 0. With regard to 9V and 5V input, I presume you mean supply voltage. So the currents you are quoting are with a full supply voltage across the FET for a very short igf530a. Thank you for this very good explanation.

But then again, if bought at the right place.

In my schematic I use an output with a small resistor Ohms in series with the gate of the N Channel Mosfet 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 dataheet second schematic.

I am using this converter: Who can tell me what should I improve i my schematic? Maybe you alreadymeasured it 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? Yes im using Arduino to control the circuit. I am actually using it with octocoupler connected to 12V. Apologies foe my late reply.

Now you want to put current through a coil. Nowadays more and more 3. For a BC it is a bit on the edge. Leave a Reply Datasjeet reply Enter your comment here Thank you for the clear explanation.

Advanced Power MOSFET

Would be interested to hear how the FET holds out on 8 Amps. Antonio, thank you for expanding. 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: I want to put around 10A of current trough a coil to make a partical accelerator. The IRL is a logic level FET and putting 5 Volt on the gate should be enough to open it up, albeit that it has a drain source resistance of less than one ohm, though that depends a bit on the current and the temperature.

Learn how your comment data is processed. The dissipation then is 5x5x0. I should turn on a load some LED lamps in paralel with a Mosfet. At 10 volt it is 4mohm and the fet can take 45 amp, but at 4.

For a mA current you then need a seriesresistor of 33 Ohm.
