Pinout of 2SC4008
Here is an image showing the pin diagram of this transistor.
Classification of hFE
The 2SC4008 transistor can have a current gain of 100 to 500. The gain of the 2SC4008-E will be in the range from 100 to 200, for the 2SC4008-F it will be in the range from 160 to 320, for the 2SC4008-G it will be in the range from 250 to 500.
Marking
Sometimes the "2S" prefix is not marked on the package - the 2SC4008 might only be marked "C4008".
Complementary PNP transistor
The complementary PNP transistor to the 2SC4008 is the 2SA1635.
SMD Version of 2SC4008 transistor
The BDP951 (SOT-223) and BDP953 (SOT-223) is the SMD version of the 2SC4008 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
