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

Classification of hFE

The 2SD745-Q transistor can have a current gain of 100 to 200. The gain of the 2SD745 will be in the range from 40 to 200, for the 2SD745-R it will be in the range from 60 to 120, for the 2SD745-S it will be in the range from 40 to 80.

Marking

Sometimes the "2S" prefix is not marked on the package - the 2SD745-Q might only be marked "D745-Q".

Complementary PNP transistor

The complementary PNP transistor to the 2SD745-Q is the 2SB705-Q.
