IRF Datasheet – MOSFETs and TempFETs from Harris Semiconductor

Also the and will be more efficient with this circuit. It doesnt look dedicated to a steppermotor though, more to drive a rgular DC motor. Rds 38mOhm with a Igf9622 of 3. The gate source resistor is purely to make a predefined state and to avoid the entrance to float I do not know the PIC18F that well, but what is important is the Output voltage it has on its pins.

See the reference below:. Oh i fully agree David. I have chosen to put one in just to be sure.

Use a baseresistor of say Ohm. You may also consider the IRLZ 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. You are commenting using your WordPress.

Do you have any idea why is the mosfet not working properly and letting the 12v works on the led strip? Thank you for the clear explanation. Is there any logic mosfet capable to dqtasheet 25 Amperes? If the steppermotor does not draw too much, think about an ULN That just will make your circuit much easier and save you a transistor and resistor.


So the currents you are quoting are with a full supply voltage across the FET for a very short time. The two P-channel mosfet will be driven by transistors. Post was not sent – check your email addresses! Thank you for your answer.

For the IRF it is even worse. By continuing to use this website, you agree to their use. The relatively cheap BUZ11 is also an option. For a BC it is a bit on the edge. You are commenting using your Twitter account. An attiny85 could do that as well. Daasheet — Great post! I will use Arduino to dim the power acording to inputs from handlebar. Not sure though what bridge you need.

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 datashewt voltage from the arduino will be 5V so the transistor will close. How we connect irf mosfethere the problem is ….

Yes im using Arduino to control the circuit. The 2n series, often used with the arduino is even worse in that aspect, but if used to switch an LED it is OK rdsOn about ohms at 4.


Do you have the break out board in the drain or the source? Looking at the curve, at a gate to source voltage of 5V the IRF is hardly turned on. The datasheet mentioned a current between 21 Amperes Amperes for driving led. They indeed can stand almost 7A, but only when sufficiently on or off. Good luck, but dont hesitate to ask again shld you need further advice.

My hairs are starting to turn gray: The STP3NA I do not know very well and I couldnt quickly find a readable datasheet, but though 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.

How can I find the current in the LED? Would like to have a non inverting driver, do you have any recommendation how to solve this, or best IC driver for arduino. What type of step up converter are you using?
