bipolar (BJT) transistor families for audio power output stages

[blueskynis]

and the list is getting to be yet more smaller..

Of course, class D is taking over.

 

[Telstar]

SiC gives us some hope for decent devices (also) for audio.

Try Toshiba's newest Power transistor for audio, TTC5200/TTA1943,See Pic.

I've searched for the pdf on these; all I can find is in Japanese. Any available in English?

Seems that this is the classicals 2SA1943/2SC5200
with a new naming scheme..

Probably, maybe trying to counter all the fakes on the market, the Cob figures are better though so maybe some small improvements made and seems these are rohs compliant.

English datasheets are available from toshiba website.

After months of waiting for an order, Ive finally received Sankens latest range 2 weeks ago, these are marketed by allegro, after some tests and these are my new favourites.

These are 2sa2223 and 2sc6145.

No; - go to
??????????? Audio????: TTA1943, TTC5200????????? ?????????
to see the differences
datasheets in english are also available there.

The slightly better sepcs of TT1943/5200 is no more
than selection at the factory output chain of the better
devices, exactly the same way that processors of different
frequency are binned...

I have used MJL1302/3281 now in this:

Great...
These are great devices, too bad i did run out of the 30 pairs
genuine toshiba i once had but who could predict that they
would be faked industrialy?...

Pavel, did you compare them with the onsemi variants that
were displayed on your schematic?..

Just curious to know the eventual differences..

Hi wahab,

in some 2 weeks I will know more, the rear panel is being milled now.

Thanks,

Hi Hugh,

http://www.semicon.toshiba.co.jp/docs/datasheet/en/Transistor/TTC5200_en_datasheet_090713.pdf

when you go to ?? ????????? | ?????? select from teh top right hand corner the english tab and it all becomes clear

 

[AKSA]

Many thanks, Luke!

Something fishy going on here, one of them power devices is held to the heatsink with a golden screw.....

 

[jacco vermeulen]

Let me guess, you're never One Philips/Mortorq screw short ?

 

[Bigun]

I wasn't being critical ...I was hoping to hear that it was the secret to a golden sound !

I've been one screw short for years !

 

[tiefbassuebertr]

Are there any news regarded post #1 ?

Special Offer from Sunspirit - 2SA1943-O + 2SC5200-O for USD1.229 / pair (EX-office )

Today I have found this offfer about this universal Toshiba power devices for audio output PP buffer stages.
Are there any experience about this supplier?
How about the risk of counterfeits resp. fakes ?
