Pinout of 2SD613
Here is an image showing the pin diagram of this transistor.
Classification of hFE
The 2SD613 transistor can have a current gain of 40 to 320. The gain of the 2SD613-C will be in the range from 40 to 80, for the 2SD613-D it will be in the range from 60 to 120, for the 2SD613-E it will be in the range from 100 to 200, for the 2SD613-F it will be in the range from 160 to 320.
Marking
Sometimes the "2S" prefix is not marked on the package - the 2SD613 might only be marked "D613".
Complementary PNP transistor
The complementary PNP transistor to the 2SD613 is the 2SB633.
SMD Version of 2SD613 transistor
The BDP953 (SOT-223) is the SMD version of the 2SD613 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
