need datasheet for D711

[mastrila]

I need to replace a power transistor in switching power supply.
The only markings on the metal case (TO-3) are "D711". Could it be a
2SD711? Can you help me find a datasheet for it?
Mastrila.

mastrila,

It is an obsolete transistor so I guess it

Hi Ante,
thanks again.
Do you know what type of transistor it is and a suitable substitute?
Mastrila.

I will look for the original but for now here is the replacement datasheet. NTE 98 or ECG98

mastrila,

One of these will do the job: BU 932, 2SD572..573, 2SD606,
BUT 51P, 2SD573, 2SD683.
