I’ve posted this circuit more than once — Go To Reply 14 For The Latest Version It’s not optimized irt530 yeah, you know, well every damn thingso it offends snarky ol’ Mr. I have a IRF connected to a 5V micro. Threshold voltage is the Vgs at which is begins to conduct just a little bit, you need way more to have good switching.

It just kept the lights on no matter what. Just trying to get a circuit working on 12v and leds before I move up to the resistance wire and 48v. This allows the temperature to stabilize, rather if530 running away. The easiest way is a logic N-channel mosfet, and switch the low side of the load. It is not specified for 5V. Your problem is insufficient Vgs for the device chosen. Trying to drive a irf mosfet with a 2n transistor. Therefore it will not conduct fully and act as a resistor.

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.

It’s very useful for connecting FETs in parallel, since if one is hogging the current, its resistance will rise and mksfet will mowfet less current, allowing equal current sharing without too much fuss ,osfet your part. Hence not the rated RdsOn. When I set the pin to high, the mosfet gets very hot.

AT the least they should rename it like Vgs Cut-Off or something that makes you think about it a different way.

Can post a schematic if you want. Email Required, but never shown. High side switching with a P-channel mosfet is another option, but more complicated. The trace is on a PCB and very short, with only a pull down resistor on the 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.

For 6A and without heatsink, aim for 15 mOhms or lower. 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?

Post as a guest Name. I am thinking the problem arises because I am sinking the negative mosfwt 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?

I will try to post what I did later mosget I get time but that is pretty much how I i wired it anders except i left out the 22k resistor.

How much does a heatsink cost vs a better FET?

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

IRF getting very hot Ask Question. Notice that at the rated voltage, the drain current will only be uA. I would like to use the 2n to push 12v to the irf50 so it fully turns on and off. You realise the logic mosfet you’re getting does not need a driver transistor. Finally, look at figure 4, Rds vs temperature, and notice how it rises.

That is a great question TonyStewart. And that 22k needs to be 1k to lower switching losses. Tony EE rocketscientist 62k 2 21 How can you choose one to keep cool? Go back to your IRF data sheet, and look at the Vgs th rating of 2 to 4 volts.

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.

If your circuit is in an aluminium case this moafet also be your heatsink. 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. The trace is on a PCB and very short, with only a pull down resistor on the gate:.

Also I assume both the mosfet and transistor here are both n type? I did order some ttl level mosfets from mosfdt they had the lowest price by far even accounting ebay unless you buy a 10 pack from china and wait.

This is in contrast with BJTs bipolar junction transistors whose effective resistance drops with rising temperature, which can lead to runaway thermal failure. Or is this just not working because I am using the same 12v supply for both mosfet and transistor.

What you’re attempting should correspond.
