Yes im using Arduino to control the circuit.

NTE – MOSFET N-Channel Enhancement, V 28A

Looking at the curve, at a gate to source voltage of 5V the IRF is hardly turned on. 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. If it does open at 3 volt and your PIC supplies that, adding a transistor is not really necesary and if you do it doesnt need to be the BC, can be a regular signal transistor too, like the The battery is ok and gives a steady 4 volts.

They are good switches,but you dont want to use them as resistors. Thanks Adriaan, Though technically it is datqsheet voltage divider, that is not really the function of it. The Vce in saturation is about 0. So, mistakes during development can be fatal.

Thank you for your answer.

It seems mosfet get burned every time. For a mA current you then need a seriesresistor of 33 Ohm. Hello ir5f30a Great post! To find out more, including how to control cookies, see here: What kind of lamp is it? Glad to be able to contribute! The STP3NA I do not know very well and I couldnt quickly find a readable datasheet, but daatsheet it doesnt seem to be a Logic level FET, from what I could see, it should open enough around 3 volt already… but if you have a better datasheet, please check that.

So if yr gate voltage is 5Volt, your source voltage will never be above that.

Dataheet, the bottom line is: Email required Address never made public. How can I find the current in the LED? I have a hard time believing it would work properly for reasons I explained earlier, but if you say it works for you… great.

These transistors will invert the signal from the N-channel mosfet, ensuring no short circuits could happen. I am not sure what voltage you need but you may try this one a 30n 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.

I will try it again after soldering it instead of using a breadboard. Like the diagram at the top of the page here.

Though that seems like the FET is suitable for an Arduino, I do not think it is an optimal combination. I seem to have missed your reply at first since I did not subscribe to your posts fast enough apparently: See the reference below:. If it would be just a wire i. What i like you to do first is to detach the pic-circuit and just put 5 Volt on the entrance of yr FET circuit, via say that ohm resistor, and see if then your lamp behaves the same.

Use a baseresistor of say Ohm. Keep an eye on the temperature though when you start using it with 8 amps.

But if it is working for you, that is good. Another thing to beware of in datasheets is Vthresh threshhold voltage. This is not the gate voltage to turn the datwsheet on, its the gate voltage at which it switches rif530a off less than a few uA of current, typically.

If you feed it with 15Volt the output voltage is around volt which will do the job. Thanks a lot for this excellent article. Thanks, I learnt few things in my new journey.

Every time I tried with new IRF, but any of them worked only for first time. Whats about this, I have check in the datasheet and seems to work very well at TTL levels even with a lot of Amps.

Thanks in advance, Ruben. Datasbeet is just there to limit the current through the gat, coming from a microcontroller pin.
