Old transistors

05.06.2007 14:08

Yesterday I found these transistors manufactured in former Yugoslavia while repairing an old EPROM programator:

BC212 equivalent in TO-92 package, from Ei Niš.

2N2907 equivalent in TO-18 package, from Radio industrija Zagreb.

Nothing special actually, except that I didn't know that they were making transistors at all.

Hi

"X1C1772 310" doesn't sound like any common transistor type designation I've seen.

Are you sure it's a transistor and not an integrated circuit of some type? Does it have a manufacturer logo? What does the package look like?

Thanks a lot by your answer I haven´t ridden before your answer

X1C1772 310 is an old metal encapsulated transistor like the metalic encapsulated
transistors of the photo up , The metal analizar has 30 years old more or less I
suppouse. And It doesnt have any manufacturer logo but the numbers are the same
type printed in the photo up.

Thanks for your Help
