Classification of hFE
The 2SB544F transistor can have a current gain of 160 to 320. The gain of the 2SB544 will be in the range from 60 to 560, for the 2SB544D it will be in the range from 60 to 120, for the 2SB544E it will be in the range from 100 to 200, for the 2SB544G it will be in the range from 280 to 560.
Marking
Sometimes the "2S" prefix is not marked on the package - the 2SB544F might only be marked "B544F".
Complementary NPN transistor
The complementary NPN transistor to the 2SB544F is the 2SD400F.
