The on resistance is not the same. Why are newbies always great in ignoring posts they don’t understand it Eatasheet – Sorry, I’m not psychic.

Wawa on Aug 14, Use fricking code tags!!!!

Thank you for your answer. It seems you’re using the wrong parts to control LED strips.

Brendan Simpson 1, 3 Wawa Shannon Member Posts: Carry on, while I go over here and hide. If this was already a way over spec’d part it would be one thing, but this is likely not true in a power supply this answer is incorrect.

Ricardo 4, 14 37 If not, is there a transistor that allows me to hookup the LEDs in a similar fashion?

Not important if you use logic fets to drive e. And you do remember how well they worked, right? Don’t care about their difference in power. I had the wrong datasheet. That would encourage people to look at them to help you.


IRFZ44N MOSFET Datasheet pdf – Equivalent. Cross Reference Search

Datawheet suggest finding a better FET, there are literally thousands of them in that package that would do the job at least as well as the OEM solution, if not better.

Unless you can be sure that both transistors are way over-spec’d for this application, you must care about the differences between them. But I agree the PCA would make more sens here. But only mA per output Here is the question: What I’m trying to say is that unless you know why the original units failed, just replacing them does not address the reason for the failure, and it may well recur.

That is to say, they may well cook too. To answer the original question: I would add a ohm resistor between chip output and gate to limit switch currents.

I guess that something’s wrecked the rail. You can hook up 12V strips directly.

iffz44n Home Questions Tags Users Unanswered. A good LED library can be found here. Mark Jhomel Olimon 11 1 4. Only the positive rail of the SMPS are cooked, but the negative rails are still in good condition.

Obviously the upper units cooked because they got hot. That shows effort, that you have tried to find your own answer, instead of laziness. Dayasheet would be better practice to show why you think this replacement might work, and ask about any aspects you are unclear on.


NEW Library igfz44n make fading leds a piece of cake https: And the fet is not a logic level fet, so can’t be driven with 5volt logic.

It can directly drive the logic level mosfets for your LED strips. So why is that sir? Two things to note: Because of this you’ll want to urfz44n a master MOSFET on the 12v line that will keep it closed until your contraption is ready for work, because if you don’t, all the strips will turn fully on on startup producing bright white.

The chip can indeed sink more current than it can source. But is will invert the PWM and you might not be able to dim datahseet to off because the leds will now be on in a blank period. It’s generally not a good idea to under-spec a replacement part, especially if the original failed in the application it was designed for. Are you certain that at the current levels this FET will be operating under that you can afford almost 2x the power dissipation? It would be polite to link to the datasheets for both parts.
