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

Classification of hFE

The 2SC108A-O transistor can have a current gain of 70 to 140. The gain of the 2SC108A will be in the range from 40 to 240, for the 2SC108A-R it will be in the range from 40 to 80, for the 2SC108A-Y it will be in the range from 120 to 240.

Marking

Sometimes the "2S" prefix is not marked on the package - the 2SC108A-O might only be marked "C108A-O".
