Which semiconductor company logo is this?

[terranigma]

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.

EDIT: Added photo

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.

Very good source but doesn't seem exist in list.

Thanks.

I put it into the websites tineye.com and revimg.com, results attached.

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.

Still looks like Aztec markings to me. Or maybe ancient Egyptian.

At least not alien

I got some photo of them. May help for curiosity a bit.

You need to ask around on a German or Hungarian website. That would check your theory that they are Soviet block production pre 1989. The only analog website I know of is the german analog organ website.
