Hi Mal,

Got following from the databook :
2N6674 - silicon NPN - TO3 package - made by RCA

max. ratings :
Vcb = 450V
Vce = 300V
Veb = 7V
Ic = 15A
Pt = 175W
Ft = 15MHz
Cob = 500pF
Hfe = >8

connections :
collector on case
if you look at it from the 'hole' that is closest to the pins then emitor
is left and base is right.

Hi all
Does anyone know what a 2N6674 transistor happens to be?
I have 4 of these devices out of a SMPS  rated at 600w. These are Motorola.
Your help appreciated de Mal/G3KEV
