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

Classification of hFE

The 2SA815 transistor can have a current gain of 70 to 240. The gain of the 2SA815-O will be in the range from 70 to 140, for the 2SA815-Y it will be in the range from 120 to 240.

Marking

Sometimes the "2S" prefix is not marked on the package - the 2SA815 might only be marked "A815".

Complementary NPN transistor

The complementary NPN transistor to the 2SA815 is the 2SC1625.
