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

Classification of hFE

The 2SD389A transistor can have a current gain of 30 to 160. The gain of the 2SD389A-O will be in the range from 80 to 160, for the 2SD389A-P it will be in the range from 50 to 100, for the 2SD389A-Q it will be in the range from 30 to 60.

Marking

Sometimes the "2S" prefix is not marked on the package - the 2SD389A might only be marked "D389A".
