Thanks Pancake plus karma I got it to work I think I confused gain drain and source on the mosfet like a newb. 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? 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? Home Questions Tags Users Unanswered. That is a great question TonyStewart.

Sign up using Facebook. The trace is on a PCB and very short, with only a pull down resistor on the gate:. Hence not the rated RdsOn.

Your problem is insufficient Vgs for the device chosen. Trying to drive a irf mosfet with a 2n transistor. More parts and slower switching.

It just kept the lights on no matter what. How many do you need? For 6A and without heatsink, aim for 15 mOhms or lower. If your circuit is in an aluminium case this can also be your heatsink.

Use 12V to drive the gate 1k pullup, 1k down divider from 24V and shutoff with an additional NPN inverter to shut off gate. Sign up using Email and Password. High side switching with a P-channel mosfet is another option, but more complicated. Sign up or log in Sign up using Google.

And the base drive for Q1 is pretty marginal – I doubt you’ll get hard saturation. Or is this just not working because I am using the same 12v supply for both mosfet and transistor. This deals with “normal” behavior, rather than worst-case.

How come this is happening?

Email Required, but never shown. 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 did order some ttl level mosfets from sparkfun they had the lowest price by far even accounting mosfrt unless you buy a 10 pack from china and wait. Even at 5 volts gate drive, you are not guaranteed to get a whole lot more than if530, and this explains your high Rds.

Threshold voltage is the Vgs at which is begins to conduct just a little bit, you need way more to have good switching. You realise the logic mosfet you’re getting does not need a driver transistor. This allows the temperature to stabilize, rather than running away. And is “on” when the Arduino is off, and could be “on” during bootup.

I will try to post what I did later when I get time ,osfet that is pretty much how I i wired it anders except i ir530 out the 22k resistor.

On shorter lengths of LEDs, it only gets marginally warm. Finally, look at figure 4, Rds vs temperature, and notice how it rises.

When I set the pin to high, the mosfet gets very hot. There are plenty of such FETs. How much does a heatsink cost vs a better FET?
