This deals with “normal” behavior, rather than worst-case.

More parts and slower switching. 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. Trying to drive a irf mosfet with a 2n transistor. And is “on” when the Arduino is off, and could be “on” during bootup. If you can mount it bare can you mount multiple irf5x0 on the same heatsink bare? Now look at figure 3.

IRF getting very hot Ask Question. TomGeorge Design and Repair of industrial control systems. There are plenty of such FETs.

IRF530 Power MOSFET

And the base drive for Q1 is pretty marginal – I doubt you’ll get hard saturation. Finally should I put a heatsink on the back of the mosfet and one on the top because I can or will that draw irt530 up through the chip and krf530 a no no? It is not specified for 5V. Sign up or log in Sign up using Google. Go back to your IRF data sheet, and look at the Vgs th rating of 2 to 4 volts.

Your problem is insufficient Vgs for the device chosen. Everything runs on smoke, let the smoke out, it stops running 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.

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. My main goal is to power some resistance wire for a heat bender. This allows the temperature to stabilize, rather than running away. It just kept the lights on no matter what. 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.

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? I am thinking the problem arises because I am sinking the negative side of the leds through the transistor instead of putting power out of the transistor should I be using a p chanel transistor to feed the mosfet its 12v to turn on?

Trying to drive a irf mosfet with a 2n transistor

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. 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. Sign up using Facebook. WhatRoughBeast 49k 2 28 You realise the logic mosfet you’re getting does not need a driver transistor. What you’re attempting should correspond.

If your circuit is in an aluminium case this can also be moset heatsink. Even at 5 volts gate drive, you are not guaranteed to get a whole lot more than this, and this explains your high Rds.

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. Or is this just not working because I am using the same 12v supply for both mosfet and transistor. High side switching with a P-channel mosfet is another moosfet, but more complicated. How much does a heatsink cost vs a better FET?

When I set the pin to high, the mosfet gets very hot. Email Mosffet, but never shown. Threshold voltage is the Vgs at which is begins to conduct just a little bit, you need way more to have good switching. That is a great question TonyStewart. How come this is happening?

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.

Hello I can make a circuit where the 2n can drive the leds and the arduino can pwm them and it works great.
