Here is an image showing the pin diagram of this transistor.
Classification of hFE
The 2SD400F transistor can have a current gain of 160 to 320. The gain of the 2SD400 will be in the range from 60 to 560, for the 2SD400D it will be in the range from 60 to 120, for the 2SD400E it will be in the range from 100 to 200, for the 2SD400G it will be in the range from 280 to 560.
Marking
Sometimes the "2S" prefix is not marked on the package - the 2SD400F might only be marked "D400F".
Complementary PNP transistor
The complementary PNP transistor to the 2SD400F is the 2SB544F.
