[sci.electronics] Source for 2SD845?

eri316@tijc02.UUCP (Ed Ingraham ) (12/14/89)

At a hamfest last year, I found a bargain power supply which needed just
a little repair work. Now I know why it was so cheap! I need to replace
some 2SD845 power transistors in it. Unfortunately this device and its
replacements are no longer manufactured and I can't find anything to
substitute which will fit the heat sink and circuit board (without major
surgery).

Here is my list of possible substitutions:

Number  Pd(W)  Ic(A) Manuf
2SD845  120    12    Toshiba    (original part)
2SC2562 150    15    Toshiba
2SC2921 150    15    Sanken
2SD745  120    10    Nippon
2SD852  100    15    Nippon
2SC2650 100    10    Toshiba
2SD851   80    10    Nippon

If anyone knows where I can find about 4 of one of these, please let me
know.

Call MCM Electronics at 1-800-543-4330 and tell 'em you want a 2SD845; they
have 'em.  You might have to buy more than one to jump over a minimum order.
