Here is an image showing the pin diagram of this transistor.The 2SC3438 transistor can have a current gain of 55 to 300. The gain of the 2SC3438-C will be in the range from 55 to 110, for the 2SC3438-D it will be in the range from 90 to 180, for the 2SC3438-E it will be in the range from 150 to 300.Sometimes the "2S" prefix is not marked on the package - the 2SC3438 might only be marked "C3438".The complementary PNP transistor to the 2SC3438 is the 2SA1368.
