It would be polite to link to the datasheets for both parts.
Home Questions Tags Users Unanswered. Wawa on Aug 14, 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. Mark Jhomel Olimon 11 1 4. Sir I was an IT student but I want to repair my Amplifier on my own, I knew a lot of things about basic electronics, however, I failed many rifz44n in troubleshooting an amplifier. Not nice and too much strain on your power supply.
But only mA per output Or do you know for certain what those values are? NEW Library to make fading leds a piece of cake https: 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. And the fet is not a logic level fet, so can’t be driven with 5volt logic. If not, is there a transistor that allows me to hookup the LEDs in a similar fashion?
A good LED library can be found here. You should see pretty much the same performance from the IRZ44Ns.
It would be better practice to show why you think this replacement might work, and ask about any aspects you are unclear on.
Wawa Shannon Member Posts: Use fricking datasneet tags!!!! Are you certain that at the current levels this FET will be operating under that you can afford almost 2x the power dissipation?
That chip if for direct driving small LEDs sink only. Obviously the upper units cooked because they got hot.
MarkJhomelOlimon – Sorry, I’m not psychic. I had the wrong datasheet. Ricardo 4, 14 37 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. Here is the question: WhatRoughBeast 49k 2 28 But I agree the PCA would make more sens here.
I 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.
Brendan Simpson 1, 3 It seems you’re using the wrong parts to control LED strips. That is to say, they may well cook too. Can I replace it without major consequences?

Two things to note: You can hook up 12V strips directly. This suggests that the gate drive circuitry and n-type MOSFETs used on the upper rails need special bootstrapped drivers is getting flakey.
Thank you for your interest in this question. Would you like to answer dahasheet of these unanswered questions instead?

Why are newbies always great in ignoring posts they don’t understand it That shows effort, that you have tried to find your own answer, instead of laziness. 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. Unless you can be sure that both transistors are way over-spec’d for this application, you must care about irtz44n differences between them.
Thank you for your answer. Only the positive rail of the SMPS are cooked, but the negative rails are still in good condition.
IRFZ44N N-Channel FET
I guess that something’s wrecked the rail. That would encourage people to look at them to help you. Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site the association bonus does not count. It can directly drive the logic level mosfets for your LED strips. The on resistance is not the same. Like an Arduino pin, it has no current limiting.
And you do remember how well they worked, right? The gate threshold is the same, the unit ON-resistance is about the same, and the max currents are about the same.
