What you’re attempting should correspond. As usual, Mr George demands every little bit documented and explained by the books theories to understand whats going on. If your circuit is in an aluminium case this can also be your heatsink. TomGeorge Design and Repair of industrial control systems. Sign up or log in Sign up using Google.

IRF530, SiHF530 product information

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?

Use 12V to drive the gate 1k pullup, 1k down divider from 24V and shutoff with an additional NPN inverter to shut off gate. Hence not the rated RdsOn.

Josfet, 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 also can make a circuit with just a irf driving some leds on 12v and it also works great. Finally, look at figure 4, Rds vs temperature, and notice how it rises.

The trace is on a PCB and very short, with only a pull down resistor on the gate: I cant get this to work. Just trying to get a circuit working on 12v and leds before I move up to the resistance wire and 48v.

Wawa Moset Member Posts: The easiest way is a logic N-channel mosfet, and switch the low side of the load. Finally should I put a heatsink on the back of the mosfet and one on the top because I can or will that draw heat up through the chip and be a no no? Trying to drive a irf mosfet with a 2n transistor. There are plenty of such FETs.

Yeah that will work. Tony EE rocketscientist 62k 2 21 At 5 irf5530 gate voltage, you can only “expect” 3 to 4 amps of current, and you want 6, so this also should give you warning. Just use a ohm resistor mpsfet Arduino port and irv530, and kohm mosfe gate to ground. Sign up using Email and Password.

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 irf350 22k resistor. Also I assume both the mosfet and transistor here are both n type?

This deals with “normal” behavior, rather than worst-case. And the base drive for Q1 is pretty marginal – I doubt you’ll get hard saturation.

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. Thanks Pancake plus karma I got it to work I think I confused gain drain and source on the mosfet like a newb.

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. Hello I can make a circuit where the 2n can drive the leds and the arduino msfet pwm them and it works great. Drive-by” that’s somebody else.

On shorter lengths of LEDs, it only gets marginally warm. This is in contrast with BJTs bipolar junction transistors whose effective resistance drops with rising temperature, which can lead to runaway thermal failure. 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.

mosfet – IRF getting very hot – Electrical Engineering Stack Exchange

Everything runs on smoke, let the smoke out, it stops running How can you choose one to keep cool? Wawa on Apr 08, Threshold voltage is the Vgs at which is begins to conduct just a little bit, you need way more to have good switching. Can post a schematic if you want. Notice that at the rated voltage, the drain current will only be uA. And is “on” when the Arduino is off, and could be “on” during bootup.

This allows the temperature to stabilize, rather than running away. Therefore it will not conduct fully and act as a resistor.

Email Required, but never shown. WhatRoughBeast 49k 2 28 My main goal is to power some resistance wire for a heat bender.

Even at 5 volts gate drive, you are not guaranteed to get a whole lot more than this, and this explains your high Rds. For 6A and without heatsink, aim for 15 mOhms or lower.
