What company calls themselves "dsi" ?

What is the full name (or website) of the company referred to in
designations like 2N3055S/DSI, BD246A/DSI, IRF140/DSI, etc. used by
component vendors?

I believe their logo too is just "dsi" in somewhat stilized, small
letters.

Thanks,
Martin.

Maybe this one? <http://www.dsi-halbleiter.de/>
Looks like they're specialised on obsolete or hard to get discretes.

Yes, theirs is the logo I had seen. And indeed they say they are
specializing in discrete semiconductors for which the original
manufacturer has stopped production. But there are no data sheets.
This leaves you wondering what you buy: A relabled compatible device
by other manufacturers? A device made by duplicating the original
process on different equipment? Or perhaps even a device still
produced by the original manufacturer, but now bearing the "dsi" logo?

You're right, it's not clear; maybe the are storing original wafers and
do the packaging on request (like Rochester, IIRC).

You might get that information by calling them.
