how odd
SO you don't have a clue huh ?
Me neither oddly confused as well.
what are you doing?
what is the data on both transistors?
Come on man tell us more.
what would you say if I said my big toe was red?

The 2SD717 is a NPN low saturation voltage switching transistor for high efficiency DC-DC converters, Vcbo=70, Vceo=50, Vebo=5, Ptot=80W, hfe= 70 to
240. IIRC the MJ2955 is a PNP designed to complement the slow old 2N3055, so if you're planning to use an MJ2955 to replace a 2SD717, make sure the smoke extractor is running before you switch on!
Yes , worked this out , will be scanning the comparison charts as locally I cant source the required device , strange your the only one with the nouse to work it out :)
The data book I got the 2SD717 info was from ECA in Germany, they also sell CD rom databases.
