Normally the impedance of a FET is high enough to not lose any signal over that resistor. Sometimes a MCU seems to be driving a mosfet correctly, but only a careful measurement will show the mosfet is not getting fully turned on, overheating and wasting power.

It start switching on at around 3V and it seems to be quite wide open at 4,5V. The IRLN can take 36 amps. Fill in your details below or click an icon to log in: I will try source a IRL So if yr gate voltage is 5Volt, your source voltage will never be above that. So the currents you are quoting are with a full supply voltage across the FET for a very short time. Somehow Logic P channel mosfetsarent as plentiful. That indeed is odd and I start to wonder if it is the IRL that is shutting down or something else.

A logic level mosfet means that it is designed to turn on fully from the logic level of a microprocessor.

Looking dtaasheet the curve, at a gate to source voltage of 5V the IRF is hardly turned on. 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.

The datasheet indicates max Urf530a 4V but the curve shows that at 5V the mosfet can deliver current way above my requirement. Leave a Reply Cancel reply Enter your comment here That is always a special situation coz of the huge spikes you can get in the coil.

Using MOSFETS with TTL levels (5 Volt and Volt) – Arduino, ESP & Raspberry Pi stuff

Great, that is good to know. Thanks for pointing out that series.

Also easier if you need to do high side switching. At 5V volt on the gate, the IRF will pass something around 4.

And a step up boost converter to supply the 5. With regard to 9V and 5V input, I presume you mean supply voltage. The battery is ok and gives a steady 4 volts. OK I try again: So, the bottom line is: Please help me out. 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.

To find out more, including how to control cookies, see here: It is not expensive: 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. How we connect irf mosfethere the problem is ….

IRFA Hoja de datos ( Datasheet PDF ) – Advanced Power MOSFET

Would be interested to hear how the FET holds out on 8 Amps. Keep an eye on the temperature though when you start using it with 8 amps. Hi, really interesting your information!!

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 irf530aa the arduino will be 5V so the transistor will close.

I will use Arduino to dim the power acording to inputs from handlebar. Notify me of new comments via email. 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.

And datasheeh i understand when you put 5 volt on the gate, the output on the source i presume is only 5Volt. Is there any logic mosfet capable to drive 25 Amperes? They indeed can stand almost 7A, but only when sufficiently on or off. If for instance you want to switch 5A in a 12V circuit and you only want to waste 0. I am getting almost 7V at the gate so no issues. If the jrf530a does not draw too much, irf530x about an ULN I have a hard time believing it would work properly for reasons I explained earlier, but if you say it works for you… great.

But if it is working for you, that is good. My hairs are starting to turn gray: The irf doesnt need 20 Volt tu turn on. Another thing to beware of in datasheets is Vthresh threshhold voltage. The IRF can obviously take 4 amps, but sadly it dstasheet a higher voltage on its gate than the most microcontrollers can deliver i presume you will use a microcontroller.

Advanced Power MOSFET

Antonio, thank you for expanding. The simplest circuit is just a 12 V regulator but that is very inefficient. If you are using this circuit to switch any serious loads, then it is wise to solder some thick wire over the tracks coming from the MOSFET. 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.

I am actually using it with octocoupler connected to 12V.
