Identifying a cracked component

Hi, tried this in s.e.r but didn't have much luck.



Just wondering if anyone could take a shot at identifying this:

A couple of the legs are missing and the colour has been changed to try and highlight the numbers.



It's a TO-92 (or very close) type package and came from a Q-Tec 650W Triple Fan 24P ATX PSU, item no 14348. The silkscreen has it identified as Q4, so maybe transistor or related? Both this and the internal fuse blew due to a short I accidentally created. All I can read is C. 44 and 447. Maybe someone could take a guess at what I think is a manufacturers logo at the top?


Many thanks



Have you checked the other transistors on the pcb? Usually, a designer uses the same type of component on the same board, so you maybe lucky and there is an identical one right there.

Thank you for the suggestion - I tried looking at the others, none matching unfortunately.

On real thin guesswork, maybe its a 2N5144. A 2N2222 is similar.
