Here is an image showing the pin diagram of this transistor.The 2SC3444 transistor can have a current gain of 55 to 300. The gain of the 2SC3444-C will be in the range from 55 to 110, for the 2SC3444-D it will be in the range from 90 to 180, for the 2SC3444-E it will be in the range from 150 to 300.Sometimes the "2S" prefix is not marked on the package - the 2SC3444 might only be marked "C3444".The complementary PNP transistor to the 2SC3444 is the 2SA1364.
