No prize, I'm afraid, but I'd really apreciate any help in identifying this component. I'm trying to find out exactly what it is so that I can check some parameters on the datasheet in order to source a replacement.
It's an N-channel MOSFET used for rail switching in a professional power amplifier and, judging from the application, I image it's rated for around 60-100Vd-s and somewhere in excess of 30A.
I have a service manual for the amplifier, which shows the transistor in this location as an IRF1010. However, the IRF1010 is rated for only 60Vd-s and the voltage across this part just slightly exceeds this - meaning that I'm not happy to simply install an IRF1010 as a replacement. I can't be confident that the schematic I'm looking at is for exactly the model of amplifier I'm working on, as there where several different power ratings in the range. Therefore I'd like to double-check the differences between the IRF1010 indicated on the schematic and this part which was actually installed on the board.
In order to make this searchable, I'll say that the text on the device reads
N313AD
75545P
and it bares the logo of Fairchild semiconductor.
Maybe someone knows the prefix that I'd have to add to make a complete part number?
In truth, it may not be that critical - but then this gear is designed by people cleaverer than me, and I'm sure thay have good reasons for the components they choose.
Thanks folks!
