Howdy all,
I am trying to track down a replacement for a transistor(?) with
the following #'s:
D829 (K)
6J2
I would like to replace it with one able to handle a higher current as I
am told they are a frequent replacement item in the circuit. Any info
would be helpful.
Thanks, Gary |

Try adding '2S' to the front of that part number. Japanese
semiconductor manufacturers have omitted it form small plastic packages
(and some others) for over 30 years.
2SD829 is the base part number, the '(K)' is the beta group, and
'6J2' is the date or batch code.

Perhaps it's this one?

If so, it's a fairly hefty NPN Darlington switch.

Some data sheet. Not even a mfr logo to claim responsibility.

I suspect that the manufacturer name may be present, albeit in
Japanese. The data sheet looks as if it might have been photocopied
from within a specific manufacturer's data book, rather than being a
stand-alone document.
If you do a search for 2SD829 at www.datasheets.org.uk, several
references come up. The first is a page from a Japanese
semiconductor-devices summary (1981, I think). The 2SD829 is listed
there... but alas, the "manufacturer" column contains only Japanese
text.
Somebody with rather better language skills than I might be able to
translate.

It looks shockingly like a Sanken device. They do some oddball packages.

Thanks, This is indeed the critter. I a hoping to find any common
replacement that is a little more hardy that will sub.
Thanks again!

No, It is Hitachi actually.
