You realise the logic mosfet you’re getting does not need a driver transistor. As usual, Mr George demands every little bit documented lrf530 explained by the books theories to understand whats going on.
And that 22k needs to be 1k to lower switching losses. I will try to post what I did later when I get time but that is pretty much how I i wired it anders except i left out the 22k resistor.
This deals mmosfet “normal” behavior, rather than worst-case.

Just trying to get irf5300 circuit working on 12v and leds before I move up to the resistance wire and 48v. TomGeorge Design and Repair of industrial control systems. AT the least they should rename it like Vgs Cut-Off or something that makes you think about it a different way.
Notice that at the rated voltage, the drain current will only be uA. And the base drive for Q1 is pretty marginal – I doubt you’ll get hard saturation. When I set the pin to high, the mosfet gets very hot. I cant get this to work. Hello I can make a circuit where the 2n can drive the leds and the arduino can pwm them and it works great.

And is “on” when the Arduino is off, and could be “on” during bootup. At 5 volts gate voltage, you can only “expect” 3 to 4 amps of current, and you want 6, so this also should give you warning.
How many do you need? How come this is happening? I’ve posted this circuit more than once — Go To Reply 14 For The Latest Version It’s not optimized for yeah, you know, well every damn thingso it offends snarky ol’ Mr.

How can you choose one to keep cool? I did order some ttl level mosfets from sparkfun they had the lowest price by far even accounting ebay unless you buy a 10 pack from china and wait.
That is a great question TonyStewart. Threshold voltage is the Vgs at which is begins to conduct just a little bit, you need way more to have good switching.
It’s very useful for connecting FETs in parallel, since if one is hogging the current, its resistance will rise and it will draw less current, allowing equal current sharing without too much fuss on your part. Finally, look at figure 4, Rds vs temperature, and notice how it rises.
Go back to your IRF data sheet, and look at the Vgs th rating of 2 to 4 volts. I am above the threshold voltage of 4V, so I assume the FET is not in a linear state, and the power dissipation according to Rds on is only 0. Now look at figure 3.
Well I looked at the data sheet and basically it doesn’t say anything about the tab or hell i didnt know to call it a tab because it doesn’t label it as that etc etc. Hi, Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png or pdf? There are plenty of such FETs.
Just use a ohm resistor between Arduino port and gate, and kohm from gate to ground.

High side switching with a P-channel mosfet is another option, but more complicated. More parts and slower switching.
IRF getting very hot Ask Question.
Wawa ir5f30 Apr 08, I would like to use the 2n to push 12v to the irf50 so it fully turns on and off. Now, it’s true that 4 volts is worst-case, and you are surely doing better than this, but it’s the heart of the problem. I am thinking the problem arises because I am sinking the negative side of the leds through the transistor instead of putting moscet out of the transistor should I be using a p chanel transistor to feed the mosfet its 12v to turn on?
Or is this just not working because I am using the same 12v supply for both mosfet and transistor.
