power supplyspecificationstransistors
It is part of a switching-mode power supply for a PC. There is a number: 1035 and a logo above this number, that seems to be a capital D. I am trying to find a replacement but it is not as easy as it should be. It is used in an arrangement of three transistors with a heatsink. Right next to a couple of big filter capacitors. The one i am looking for appears twice next to the third/first (dont know what should be the order), a SPS S18-0703 E3150 transistor (apparently, +5V stanby).
Yes. Give us the circuit and we will be able to spec a transistor for you.
AND a photo to go on with (and comment on thos below).
A copper side view of PCB as well would help muchly (for the terminally enthused to start in on).
If you have a working unit so much the better.
I you can tell us the supply voltage, power taken and frequency it would help greatly. That would be enough to hazard a good gusstimate. Even voltage would possibly be enough !!!
BUT the more you tell us the better.
For example, telling us that it was in a metal T03 case on a heatsink about xxx big and was made in 2008 or ... would help.
eg - like this? Yes? :-)
May be used elsewhere in system, too? Board level parts supplier here says
Item # Description Price
SS8G-PCA080 Generator Board, Acousti-pulse 6580 $91.91
SS8G-PCA120 Generator Board, Acousti-pulse 6580 $91.91
and... . Transistor is about certain to be the same given the peep of part number seen.
Item # Description Price
SS8G-PCA120X2 Generator/Driver Acousti-Pulse/Dual $165.44
You didn't tell us you knew board part numbers !!!! More photos
2n2222 is all you need to know. It is a standard kind of transistor made by many manufacturers. (In fact it is the single most common kind of transistor.) Go to one of the websites that does retail sales of electronic components (e.g., Jameco, Digikey, Mouser). Type "2n2222" into the search box. Click on the first transistor that comes up. Somewhere on that page will be a link that is labeled "data sheet". Click on it. You will get a pdf file (from some random manufacter) that lists the specs.
Here is the one (from ON Semi) that I got when I did this at Digikey just now.

No picture? Anyway, if it is in a TO-220 package, then it looks like it might be an old Fujitsu (early 1980's) NPN BJT. A "2SD1035."
But that's just a guess given the D and the number you mentioned.
