Default Which semiconductor company logo is this?

Hello All,

I have some BC550's with this logo. I remember that I saw this logo somewhere but can't recognize it. Probably one of the big companies' former logo.

Regards.

150 views but no opinion given yet. Can this be from a Soviet era Eastern Europe semiconductor manufacturing plant? No bad far a 650 Hfe part then.

Thank you guys.

I think the site below can't be matched in logo collecting category:

How to identify integrated circuit (chip) manufacturers by their logos - a great resource for How To's from Wikia

But no luck.

Put up a closeup of the device?

Also look at the date code and also how the device is marked.

I'm going to guess this is a china made device if you can't find a logo anywhere by a normal search.

My macro capable camera has stolen thus I tried to depict the logo rather giving a photo. But I will post a photo anyway.

There is no date mark. There is a "n" just nearby logo. It is probably 20 years old maybe even older. It is hard to find info about East European, Soviet era semiconductor products also. I suspect that my BC500's fall into this category. I'm updating the logo.

The 'n' is not Cyrillic.
