How much does a heatsink cost vs a better FET? Use 12V to drive the gate 1k pullup, 1k down divider from 24V and shutoff with an additional NPN inverter to shut idf530 gate. And is “on” when the Arduino is off, and could be “on” during bootup. 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?

If your circuit is in an aluminium case this can also be your heatsink.

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

As usual, Mr George demands every little bit documented and explained by the books theories to understand whats going on. Everything runs on smoke, let the smoke out, it stops running This deals with “normal” behavior, rather than worst-case. 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? Drive-by” that’s somebody else. How can you choose one to keep cool?

Post as a guest Name. What you’re attempting should correspond. It just kept the lights on no matter what. Yeah that will work. 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. I also can make a circuit with just a irf driving some leds on 12v and it also works great. That is a great question TonyStewart.

My main mosfrt is to power some resistance wire for a heat bender. How come this is happening? If you can mount it bare can you mount multiple irf5x0 on the same heatsink bare?

Your problem is insufficient Vgs for the device chosen. Home Questions Tags Users Unanswered.

Also I assume both the mosfet and transistor here are both n type? Finally, look at mosfdt 4, Rds vs temperature, and notice how it rises. I’ve posted this circuit more than once — Go To Reply 14 For The Latest Version It’s irt530 optimized for yeah, you know, well every damn thingso it offends snarky ol’ Mr.

Just use a ohm resistor between Arduino port and gate, and kohm from gate to ground.
