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. This is in contrast with BJTs bipolar junction transistors whose effective resistance drops with rising temperature, which can lead to runaway thermal failure. The easiest way is a logic N-channel mosfet, and switch the low side nosfet the load.

mosfet – IRF getting very hot – Electrical Engineering Stack Exchange

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. If you can tell me what page and what piece of info says it on the datasheet maybe i can learn where to look next time.

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. Irv530 can you choose one to keep cool? Sign up using Email and Password. I cant get this to work. Sign up or log in Sign up using Google.

As usual, Mr George demands every little bit documented and explained by the books theories to understand whats going on. What you’re attempting should correspond. IRF getting very hot Ask Question.

The trace is on a PCB and very short, with only a pull down resistor on the gate: Everything runs on smoke, let the smoke out, it stops running Tony EE rocketscientist 62k 2 21 Or is this just not working because I am using the same 12v supply for both mosfet and transistor. It just kept the lights on no matter what. Hello I can make a circuit where the 2n can drive the leds and the arduino can pwm them and it works great. Go back to your IRF data sheet, and look mosft the Vgs th rating of 2 to 4 volts.

Finally, look at figure 4, Rds vs temperature, and notice how it rises. You realise the logic mosfet you’re getting does not need a driver transistor.

Yeah that will work. When I set the pin to high, the mosfet gets very hot. And is “on” when the Arduino is off, and could be “on” during bootup. It is not specified for 5V. High side switching with a P-channel mosfet is another option, but more complicated.

There are plenty of such FETs. Wawa on Mofset 08, WhatRoughBeast 49k 2 28 More parts and slower switching. 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.

Even at 5 volts gate drive, you are not guaranteed to get a whole lot more than this, and this explains your high Rds.

Drive-by” that’s somebody else. How many do you need? While others have adequately answered the question, I thought I’d approach it from another perspective, in order to give you some insight as to how to read data sheets.

And that the posted circuit inverts change your code. Use 12V to drive the gate 1k pullup, 1k down divider from 24V and shutoff with an additional Moxfet inverter to shut off gate. 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 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.

Trying to drive a irf mosfet with a 2n transistor.

I have a IRF connected to a 5V micro. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. I am thinking the problem iff530 because I am sinking the negative side of the leds through the transistor instead of putting mosget out of the transistor should I be using a p chanel transistor to feed the mosfet its 12v to turn on?
