And you do remember how well they worked, right?

It seems you’re using the wrong parts to control LED strips. 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.

IRFZ44N N-Channel FET

Carry on, while I go over here and hide. It would be polite to link to the datasheets for both parts. But I agree the PCA would make more sens here.

Not important if you use logic fets to drive e. That shows effort, that you have tried to find your own answer, instead of laziness. Brendan Simpson 1, 3 Here is the question: I had the wrong datasheet. 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 times in troubleshooting an amplifier.

This suggests that the gate drive circuitry and n-type MOSFETs used on the upper rails need special bootstrapped drivers is getting flakey. MarkJhomelOlimon – Sorry, I’m not psychic. Like an Arduino pin, it has no current limiting.


Wawa on Aug 14, That would encourage people to look at them to help you. Unless you can be sure that both transistors are way over-spec’d for this application, you must care about the differences between them. 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.

Can I replace it without major consequences?

So why is that sir? Or do you know for certain what those values are? You should see pretty much the same performance from the IRZ44Ns. Two things to note: 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. Are you certain that at the current levels this FET will be operating under that you can afford almost 2x the power dissipation?

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.

To answer the original question: That is to say, they may well cook too. Only the positive rail of the SMPS are cooked, but the negative rails are still in good condition. WhatRoughBeast 49k 2 28 Not nice and too much strain on your power supply.

That chip if for direct driving datawheet LEDs sink only. NEW Library to make fading leds a piece of cake https: It would be better practice to show why you think this replacement might work, and ask about any aspects you are unclear on.

Mark Jhomel Olimon 11 1 4. Would you like to answer one of these unanswered questions instead?

But only mA per output Home Questions Tags Users Unanswered. You can hook up 12V strips directly. Ricardo 4, 14 37 Thank you for your interest in catasheet question. A good LED library can be found here. The gate threshold is the same, the unit ON-resistance is about the same, and the max currents are about the same. If not, is there a transistor that allows me to hookup the LEDs in a similar fashion?

The chip can indeed sink more current than it can source.

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. Wawa Shannon Member Posts: Use fricking code tags!!!!

The on resistance is not the same.
