Here is an image showing the pin diagram of this transistor.

Classification of hFE

The 2SD812-R transistor can have a current gain of 40 to 80. The gain of the 2SD812 will be in the range from 40 to 200, for the 2SD812-P it will be in the range from 100 to 200, for the 2SD812-Q it will be in the range from 60 to 120.

Marking

Sometimes the "2S" prefix is not marked on the package - the 2SD812-R might only be marked "D812-R".

Complementary PNP transistor

The complementary PNP transistor to the 2SD812-R is the 2SB747-R.

SMD Version of 2SD812-R transistor

The BDP951 (SOT-223) is the SMD version of the 2SD812-R transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
