Here is an image showing the pin diagram of this transistor.
Classification of hFE
The 2SC4512 transistor can have a current gain of 50 to 180. The gain of the 2SC4512-O will be in the range from 50 to 100, for the 2SC4512-P it will be in the range from 70 to 140, for the 2SC4512-Y it will be in the range from 90 to 180.
Marking
Sometimes the "2S" prefix is not marked on the package - the 2SC4512 might only be marked "C4512".
Complementary PNP transistor
The complementary PNP transistor to the 2SC4512 is the 2SA1726.
SMD Version of 2SC4512 transistor
The BDP953 (SOT-223) is the SMD version of the 2SC4512 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
