You should see pretty much the same performance from the IRZ44Ns. It would be polite to link to the datasheets for both parts. Mark Jhomel Olimon 11 1 4.

IRFZ44N N-Channel FET

Not nice and too much strain on your power supply. But I agree the PCA would make more sens here. I would add a ohm resistor between chip output and gate to limit switch currents. And you datasheett remember how well they worked, right? Carry on, while Datashheet go over here and hide. Wawa Shannon Member Posts: Two things to note: Or do you know for certain what those values are? It seems you’re using the wrong parts to control LED strips.

That is to say, they may well cook too. The chip can indeed sink more current than it can source.

Home Questions Tags Users Unanswered. 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.

Are you certain that at the current levels this FET will be operating under that you can afford almost 2x the power dissipation? To answer the original question: A good LED irfz444n can be found here.


Unless you can be sure that both transistors are way over-spec’d for this application, you must care about the differences between them. This suggests that the gate drive circuitry and n-type MOSFETs used on the upper rails need special bootstrapped drivers is getting flakey.

Here is the question: By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. But only mA per output Sir I was an IT student krfz44n I want to repair my Amplifier on my own, I knew a lot of things about basic electronics, however, I failed many times in troubleshooting an amplifier. Because it has attracted low-quality or spam answers that had to be removed, irffz44n an answer now requires 10 reputation on this site the association bonus does not count.

Would you like to answer one of these unanswered questions instead? 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. Thank you for your answer. Because of this you’ll want to add 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.

MarkJhomelOlimon – Sorry, I’m not psychic. WhatRoughBeast irffz44n 2 28 I guess that something’s ddatasheet the rail.

Wawa on Aug 14, datashdet, Brendan Simpson 1, 3 I irz44n 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. It would be better practice to show why you think this replacement might work, and ask about any aspects you are unclear on. 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.

Obviously the upper units cooked because they got hot. That would encourage people to look at them to help you.

Don’t care about their difference in power. NEW Library to make fading leds a piece of cake https: Only the positive rail of the SMPS are cooked, but the datasheeg rails are still in good condition. Like an Arduino pin, it has no current limiting.

That chip if for direct driving small LEDs sink only. Thank you for your interest in this question. But is will invert the PWM and you might not be able to dim fully to off because the leds will now be on in a blank period. Why are newbies always great in ignoring posts they don’t understand it The on resistance is not the same. Daatasheet fricking code tags!!!!

Not important if you use logic fets to drive e. A PCA breakout board Adafruit or ebay could do what you want. I had the wrong datasheet. datasjeet

You can hook up 12V strips directly. Can I replace it without major consequences?

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.
