Hey, i have about 10 of these transistors, at least i think that's what they are, quick inspection with DMM gave results indicating NPN transistor. case is same as 2n3055, TO-3. Sadly, i cant find any information from google. markings on component are : F801, PD1515, hongkong. See photo for better image :). I scavenged these from old linear PSU.

Thanks in advance! :).

Sorry, i couldn't find it from that link, but according to that image, and other clues from that link, some sort of voltage regulator?

Dear Fezder,
As I requested you in PM to atleast let me know which Company's Model Linear PSU you found these PD1515 Transistors?
Have you used PD1515's in any of your projects?

Thanks !
