Need Datasheet for D2065

[hotwaterwizard2]

This is a Transistor D2065 [M] printed on it which is Matsushita which is now Panasonic.
I figure it is a 2SD2065 NPN Transistor.
It is in a Kenwood KAC-624 Carstereo Amplifier.
There are 4 of them in the Audio Output Stage of the Amplifier.
What is curious about this Amplifier is all output transistors are the same not compliment pairs . The Transistor Gets Hot and shuts down and one or more of these transistors are bad. I need a Datasheet for this so I can see if any of the Transistors I currently have will work in place of this Obsolete Transistor.

It is a discontinued device John..
I found this spec..

Vmax = 140 Volts
IcMax = 7.0 Amp
Pmax = 80 Watts
hFE?

I believe the D in the part number stands for Darlington and this does not look like a Darlington replacement.

Hi, John

I found the info in a book, and now I found it on the net also: http://perso.wanadoo.fr/pouzou/site/composants/sd/2s2000.htm

Good Luck!

Oh, I forgot:
Here are some datasheets for the nearest brother and for the equivalent one.
By the way the

And the other one!

2sc2837.pdf

 

[hotwaterwizard2]

I found both of those too It just Gets me that I can find All of these Exact Datasheets for Everyone else but, I can't get the exact one for a simple Transistor for myself. Man it buggs me bad!!!

Well John, that

Hi John

Some research in old books:
2SD2065 :NPN power/audio/switch ,140Volts 7A 80W
Can be replaced with BD245D 2SC2706 2SC2837 2SC3907
Question : Does the 2SD2065 have an insulated case?
One of my books states that the comparison type does not have insulated case, so makes me wonder :-\
