The same dies may still be available in the MT100 case. Smaller ones in the same family certainly will be.

Yes, the 2922/1216 available as 3519/1386, of can choose the better 6145/2223..

TO-92, 126, 218..... poof. TO-264 is probably next. We'll just have to live with the cheaper TO-3P versions.

I was sad when Toshiba finished the 5171/1930, but they started the TTC/TTA004 instead. So, the future is dark, but not hopeless...

I'm glad I picked up a couple not to long ago and almost cleaned out Profusion.:D:D:D They measured quite tight Hfe spread. :)

Well, this is disappointing. I was hoping to use these in a future project. Perhaps its better to wait and see what options will show up when I'm ready.

Although, it looks like someday in the not so distant future DIY will consist of sending a schematic in and having a discrete IC printed for you(at a price no one can pay). Just add power & ground!
 
Since the big, rounded CRT TV sets were abandoned, a long list of great, cheap high-voltage transistors and other components have been gradually abandoned too. The rest have turned to SMD of course.
SMD has its pros and cons in comparison to through-hole ones. I don't see any other option, than adapt.
A good soldering station with a hot-air pencil and practice, is a must.

Actually, you will only have to "send" a block diagram to your IC printer, and most likely that will be in the near future and you'll be able to print displays too. ;)
The DIY ICs might be much bigger, but functional at a low cost, eg a complete device could be made as a large flat chip up to a printer page -fully integration age with no discrete components whatsoever :).

Where's the notice of discontinuation ? Cant find anything about it on Sanken's site.

They are buried in the list.

Just IMHO I don't miss the MT200 packages. :)
One can get roughly 6 pcs of equivalent TO-3P devices for the same price as 4 pcs of MT200, inside it the silicon substrate is still attached onto a TO-3P metal base which in turn is attached to a larger MT200 base, paying ~2 €$£ more for extra metal and plastic huh? :D

I feel too old myself, to work with smd-s. Few is OK, but soldering hudreds of them are out of question. My only way is to stock as much through hole devices as I can...
