Classification of hFE
The 2SB544G transistor can have a current gain of 280 to 560. 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 2SB544F it will be in the range from 160 to 320.
Marking
Sometimes the "2S" prefix is not marked on the package - the 2SB544G might only be marked "B544G".
Complementary NPN transistor
The complementary NPN transistor to the 2SB544G is the 2SD400G.
SMD Version of 2SB544G transistor
The BC808 (SOT-23), BC808-40 (SOT-23), BC808-40W (SOT-323) and BC808W (SOT-323) is the SMD version of the 2SB544G transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
