Pinout of 2SC2238
Here is an image showing the pin diagram of this transistor.
Classification of hFE
The 2SC2238 transistor can have a current gain of 70 to 240. The gain of the 2SC2238O will be in the range from 70 to 140, for the 2SC2238Y it will be in the range from 120 to 240.
Marking
Sometimes the "2S" prefix is not marked on the package - the 2SC2238 might only be marked "C2238".
Complementary PNP transistor
The complementary PNP transistor to the 2SC2238 is the 2SA968.
