Pinout of 2SC4511
Here is an image showing the pin diagram of this transistor.
Classification of hFE
The 2SC4511 transistor can have a current gain of 50 to 180. The gain of the 2SC4511-O will be in the range from 50 to 100, for the 2SC4511-P it will be in the range from 70 to 140, for the 2SC4511-Y it will be in the range from 90 to 180.
Marking
Sometimes the "2S" prefix is not marked on the package - the 2SC4511 might only be marked "C4511".
Complementary PNP transistor
The complementary PNP transistor to the 2SC4511 is the 2SA1725.
SMD Version of 2SC4511 transistor
