For example, when used with a high frequency PWM and high amps, careful testing must be done, because high frequency means more time spent in the linear zone, and these parts can quickly get hot and burn, differently of TO parts, that can also burn, but only after some minutes of overheating. This is not 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.
Thanks for your contribution. My hairs are starting to turn gray: Then indeed the FET will open but it cannot go above 5Volt at the source, because then it will close again as the VGStsh is around Also easier if you need to do high side switching.

Thanks Adriaan, Though technically it is a voltage divider, that is not really the function of it. Do you have any idea why is the mosfet not working properly and letting the 12v works on the led strip?
More and more cheap Mosfets. My dilemma is am new to this field so is there any other better power MOSFET for high voltage switching application and driver for the same. Thanks for pointing out that series. The battery is ok and gives a steady 4 volts. Would be interested to hear how the FET holds out on 8 Amps.
Thanks — You are correct. So, mistakes during development can be fatal. I am not sure where you are based but the IRL costs abt 60 cts where I am. Thanks a lot for this datsaheet article. Who can tell me what should I improve i my schematic? Fill in your details below or click an icon to log in: And as i understand when you put 5 volt on the gate, the output on the source i presume is only 5Volt.
The circuit should be robust enough to support the load during a few minutes. 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.
The datasheet indicates max Vgs 4V but the curve shows that at 5V the mosfet can deliver current way above my requirement.
It doesnt look dedicated to a steppermotor though, more to drive a rgular DC motor. Try just to test without the datxsheet, 3. Sorry no T2 and R1.
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.
Antonio, thank you for expanding. Thanks very much for your time. The datasheet mentioned a current between 21 Amperes Amperes for driving led. But to be sure datashret had a question. 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. If irl20n would be just a wire i. Perhaps it is a lose wire or something.
Much better to use a cheap Darlington transistor then. It shows the same behaviour when I use 3. For a BC jrl520n is a bit on the edge. The IRF can obviously take 4 amps, but sadly it expects a higher voltage on its gate than the most microcontrollers can deliver i presume you will use a microcontroller.

See the reference below:. 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.
Whats about dataasheet, I have check in the datasheet and seems to work very well at TTL datashedt even with a lot of Amps. Thank you for this very good explanation.
But if it is working for you, that is good. 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. I will use Arduino to dim the power acording to inputs from handlebar. A logic level mosfet means that it is designed to turn on fully from the logic level of a microprocessor. I am not sure what datasheet you looked at but I do not see a max of 4Volt, I see a max datasheft ca 20 Volt.

This actually is used for heatedbed in 3D printers up to A. Looking at the curve, at a gate to source voltage of 5V the IRF is hardly turned on. I was not aware of those. 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. With regard to 9V and 5V input, I presume you mean supply voltage.
