Classification of hFE
The 2SD809-L transistor can have a current gain of 135 to 270. The gain of the 2SD809 will be in the range from 135 to 600, for the 2SD809-E it will be in the range from 360 to 600, for the 2SD809-F it will be in the range from 300 to 480, for the 2SD809-K it will be in the range from 200 to 400.
Marking
Sometimes the "2S" prefix is not marked on the package - the 2SD809-L might only be marked "D809-L".
SMD Version of 2SD809-L transistor
The 2SD1615A (SOT-89) and 2SD1615A-GQ (SOT-89) is the SMD version of the 2SD809-L transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
