No, but it's in my Japanese transistor book (I can't tell you the proper
title because it's in Japanese :-))
Yes, it's a PNP power trannie, in an ATV package, which is a bit like a
TO220 but without the metal tab. It has a beveled edge on the front top,
instead of a metal tab on the back.
Vcbo -60V
Vceo -50V
Ic(max) -3A
Pc 1W
Icbo -10microA
Vcb -40V
hFE min 56 max 390 at Vce=-3V Ic -0.5A
Vce(sat) -1V
Vbe(sat) -1.5V
Ft 100MHz
Pin order is ECB (opposite of the common TO220).
Near equivalent 2SD1864.
