Custom DirectFet on retina logic board?

Hi everybody,

I am desperately trying to fix my poor Macbook Pro retina 15 that suffered a damage from coffee spill. The damage seems restricted to just one single smd component, the bad news for me is that it does not appear in any datasheet.

It's an International Rectifier smd component with part number 1010, probably a directFet.

Here is a high res photo:

Is it possible that Apple uses custom made component not available on the market? i cannot find it anywhere...

Thanks to anybody who can give me some clue on that or a possible replacement.

Best,

Alessandro

Alessandro, what are the last three digits of your serial number? This may help us to try to find out more about the logic board.

Alessandro, start of with this part marking.

Thanks to fortunato for looking at this questions, otherwise I would have never thought of it again. Anyhow, the component you are looking for is reference designator Q7510 and it is a IRF6802SDTRPBF MOSFET 25V Dual Control FET. The datasheet is available right here. Hope this helps to finally answer this question.

OT - Have you found a source for these odd ball parts Apple uses? Also have you tried to replace these flat-pak SMD devices? Four leads/pads is as far as I can take it with a straight micro iron and a good probe to hold it in place. These look harder to work with.

Dan, just looked up a similar one from an A1286, it's a IRF9395TRPBF with the datasheet available here http://www.irf.com/product-info/datashee... definitely interesting and sure looks like a PITA to work with. Still trying to find the right one for Alessandro. they are definitely International Rectifier

Thank you very much for your help.

The logic board has got a black sticker, I suppose it's the serial number you are asking for and it ends with "VAH"

The macbook serial number is printed on the botton of the machine and ends with "DKQ1".

The exact model number of my retina is A1398, it's a 2.3ghz i7 8GB ram 256 ssd.

Component part number is "1010" but it is for sure an OEM part number for Apple, IRF support confirmed that but was not able to tell me more.

Thanks again

Cheers,

Alessandro

OT - Looks like you need to modify the heat gun, creating a concentrator cone to limit the air stream to selectively heat the area. - I had a thought, what if we tried using their online design tool to input the known voltages and see what BOM and circuit it spits out and see it it matches what Apple has. Or, compare their other FET's they use in the other MBP power circuits maybe we can glean a clue that way.

Dan- that is a pretty decent idea. Let's see what we can come up with....
