I have googled and i cant seem to find any info on a M50D060S Semi device used in a switching power supply. I think its a 600V 50 amp IGBT, or possibly a mosfet.
Anyone have any info???
What is the equipment. it would not be at all unlikely it is a house number.
And as to google, if that whole number is not all on one line, try parsing it as some could be a date code instead fo part of the part number.
I just googled M50D06 and go a pile of data sheet hits, many of which mention M50D060S as well.
Thank you! I have found a site that was in Russian that mentioned that part number and datasheet. I managed to find it but was unsure if it was in fact the correct item.
That's a pretty hefty IGBT!! I spent a great deal of time trying to find a cross referenced match and nothing i found has the same specs at 100 dec C.
Please take a look at these two parts and tell me if one would work better then the other and if either are a close enough match??
I think the Fairchild product specs look a bit better. a bit higher rated. But i have always had good luck with IRF stuff.
This is a switching power supply for a Behringer Mixer/Amp with a high powered stereo amp section. I expect it will be abused by its users and the amp pushed to clip quite often.
As i understand it. Yamaha uses these same components in there products.
Thanks Enzo, I spent about hour and a half googling, bling-ing, yahoo-ing every possible way! I usually do that first and then when i have given up i post here! LOL! and usually someone here has the info right away!
the Fairchild part passes the 50A at 100C mark, no ?
IXYS manufactures similar/higher spec IGBTs, e.g. IXGK50N60B, likely cheaper.
Or Advanced Power parts, like APT40GP60B(+something)
I suppose that the package is the limiting problem.
Behringer PMP880S, 3000 and PMP5000.
Mmm, speaking of a nice rock solid package.
The IRF Part does 45A @ 110 Deg C which is close.
I have two of these Mixers both with failed power supplies. I have no doubt they get the crap beat out of them so upgrading those IGBT's a little bit wouldn't hurt. and the Fairchilds are rated at 75A @ 25deg C so maybe they will survive a bit longer. But please advise if the rest of the specs look like they match close enough????
I looked at all the IXYS stuff that Digikey has and nothing came as close as the Fairchild. and I haven't looked at the APT Stuff.
These Behringer are quite a piece of S***t, when it comes down to repairing them. I found a company that sells complete electronic modules at really convenient price(ex. a brand new power supply of the PMP5000 costs around 150€+shipping costs).
just while writing this reply, I have one on my desk with burnt IGBTS.
I give you an example of bad design: Look at the Power Integrations web page and find the application note for the TOP221(in Behringers it is used to power the control circuitry of the main PSU). You will see, that there is a component (in parallel with the primary of the transformer), a clamp diode, to absorb the peaks of energy developed by the primary winding when the power transistor in the TOP221 is not conducting. These peaks are even bigger when the small power supply approaches some overload condition(like a short circuit). Then all the energy stored in the output inductance gets multiplied by the transformer ratio back to the primary and it very easily destroy the TOP221 and associated components. On Behringers you won't find such a diode - a mistake in the design. My belief is that the entire Behringer(also known as Berlinguer...) PSU is full of this kind of design mistakes which lead to it's premature failure.
(the C15 also is critical for the correct operation of the Half Bridge topology PSU and in Behrigers is rated at 400V!?)
However all the components are on stock at Farnell.

yeah i gave up on mine. I checked every component on the PSU replaced all that were bad, crossed my fingers and fired it up...nothing, checked and checked again...nothing.. then while it was on i started checking voltages and after a minute or two it started making noise like it was trying to run and before i could get to the power switch POOF away it went again.....Junk!
I made a step forward in repairing the PMP5000. I repaired the power supply, tested it on bench(without the power amp module), it worked fine(loaded with a 500W lightbulb across the +/-80V outputs).
I performed all the testing with an isolation variac.
When I connected the power amp, then I almost got fireworks again...
One of the channels is defective and it kept the HV output of the PSU shorted.(Fortunately I powered the stuff with the variac and I was rising the voltage slowly)
Now I'm facing the problem of Behringer hiding the datasheets of the HCA9001 and similar stuff.
I will probably have to replace the entire power amp module.:att'n:
I promised to myself: once I'm finished with this, to NEVER REPAIR BEHRINGERS AGAIN!!!
