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.

The trace is on a PCB and very short, with only a pull down resistor on the gate:.

Notice that at the rated voltage, the drain current will only be uA. Can post a schematic if you want. Go back to your IRF data sheet, and look at iff530 Vgs th rating of 2 to 4 volts.

And that the posted circuit inverts change your code. For 6A and without heatsink, aim for 15 mOhms or lower. How come this is happening?


Trying to drive a irf mosfet with a 2n transistor. Use 12V to drive the gate 1k pullup, 1k down divider from 24V and shutoff with an additional NPN inverter to shut off gate. This deals with “normal” behavior, rather than worst-case. My main goal is to power some resistance wire for a heat bender. Hence not the rated RdsOn. Just use a ohm resistor between Arduino port and gate, and kohm from gate to ground. Home Questions Tags Users Unanswered.


How many do you need? The easiest omsfet is a logic N-channel mosfet, and switch the low side of the load.

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

If you can mount it bare can you mount multiple irf5x0 on the same heatsink bare? Wawa on Apr 08, WhatRoughBeast 49k 2 28 That is a great question TonyStewart. I also can make a circuit with just a irf driving some leds on 12v and it also works great.

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.

Even at 5 volts gate drive, you are mosvet guaranteed to get a whole lot more than this, and this explains your high Rds. This is in contrast with BJTs bipolar junction transistors whose effective resistance drops with rising temperature, which can lead to runaway thermal failure. Yeah that will work. Drive-by” that’s somebody else.

I would like to use the 2n to push 12v to the irf50 so it fully turns on and off.

Hello I can make a circuit where the 2n can drive the leds and the arduino can pwm them and it works great. If your circuit is in an aluminium case this can also be ,osfet heatsink. 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? Threshold voltage is the Vgs at which is begins to conduct just a little bit, you need way more to have good 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. On shorter lengths of LEDs, it only gets marginally warm.

Finally, look at figure 4, Rds vs temperature, and notice how it rises. 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 mpsfet 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. 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.
