Wawa on Aug 14, 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.

You should see pretty much the same performance from the IRZ44Ns. 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.

WhatRoughBeast 49k 2 28 MarkJhomelOlimon – Sorry, I’m not psychic. A good LED library 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.

Home Questions Tags Users Unanswered. It seems you’re using the wrong parts to control LED strips. And you do remember how well they worked, right? 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. But I agree the PCA would make more sens here. If not, is there xatasheet transistor that allows me to hookup the LEDs in a similar fashion? Or do you know for certain what those values are?


That is to say, they may well cook too. 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.

IRFZ44N N-Channel FET

Don’t care about their difference in power. 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. And the fet is not a logic level fet, so can’t be driven with 5volt logic.

It would be polite to link to the datasheets for both parts. If this was already a way over spec’d part it would be one thing, but this is likely datxsheet true in a power supply this answer is incorrect.

Obviously the upper units cooked because they got hot.

That shows effort, that you have tried to find your own answer, instead of laziness. Wawa Shannon Member Posts: NEW Library to make fading leds a piece of cake https: It would datashert better practice to show why you think this replacement might work, and ask about any aspects you are unclear on. The gate threshold is the same, the unit ON-resistance is about the same, and the max currents are about the same. The chip can indeed sink more current than it can source.

That chip if for direct driving small LEDs sink only. Carry on, while I go over here and hide. Ricardo 4, 14 37 I had the wrong datasheet. Are you certain irzf44n at the current levels this FET will be operating under that you can afford almost 2x the power dissipation?

I guess that something’s wrecked the rail.

Two things to note: You can hook up 12V strips directly. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.
