Here is an image showing the pin diagram of this transistor.The 2SC4388-O transistor can have a current gain of 50 to 100. The gain of the 2SC4388 will be in the range from 50 to 180, for the 2SC4388-P it will be in the range from 70 to 140, for the 2SC4388-Y it will be in the range from 90 to 180.Sometimes the "2S" prefix is not marked on the package - the 2SC4388-O might only be marked "C4388-O".The complementary PNP transistor to the 2SC4388-O is the 2SA1673-O.
