"Spehro Pefhany"


** Appears to be an obsolete type.

Several references quote the " MJE3055T " as being a replacement with
similar or better specs.

Gack! Well, you can bolt it in the same place and the pinout is the
same, but things kinda fall apart from there.. considering the ft of
the 3055 is 2MHz vs 100MHz for the 2SC2397.



** The Motorola " POWER Data Book" of 1982, lists the devices as "similar
replacements" - as does the similar " Bipolar Power Transistor Data " of
1987.

I found at least 7 web sites, including the ST Microelectronics site, with
the same info.

Seems some staffer at Motorola made an error in the early 80s and it has
gone on and on and on ........
