hotwaterwizard Posted April 17, 2004 Report Share Posted April 17, 2004 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. Quote Link to comment Share on other sites More sharing options...
Guest Kasamiko Posted April 17, 2004 Report Share Posted April 17, 2004 It is a discontinued device John..I found this spec..Vmax = 140 VoltsIcMax = 7.0 AmpPmax = 80 Watts hFE? Quote Link to comment Share on other sites More sharing options...

hotwaterwizard Posted April 17, 2004 Author Report Share Posted April 17, 2004 I believe the D in the part number stands for Darlington and this does not look like a Darlington replacement. Quote Link to comment Share on other sites More sharing options...
ante Posted April 17, 2004 Report Share Posted April 17, 2004 Hi, JohnI found the info in a book, and now I found it on the net also: http://perso.wanadoo.fr/pouzou/site/composants/sd/2s2000.htmGood Luck!Ante ::) Quote Link to comment Share on other sites More sharing options...
ante Posted April 18, 2004 Report Share Posted April 18, 2004 Oh, I forgot:Here are some datasheets for the nearest brother and for the equivalent one. By the way the 2SD2064.pdf Quote Link to comment Share on other sites More sharing options...

hotwaterwizard Posted April 18, 2004 Author Report Share Posted April 18, 2004 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!!! Quote Link to comment Share on other sites More sharing options...

ante Posted April 19, 2004 Report Share Posted April 19, 2004 Hi JohnSome research in old books:2SD2065 :NPN power/audio/switch ,140Volts 7A 80W Can be replaced with BD245D 2SC2706 2SC2837 2SC3907Question : 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 :-\Ante ::) Quote Link to comment Share on other sites More sharing options...
