Here is an image showing the pin diagram of this transistor.The 2SD438-G transistor can have a current gain of 280 to 560. The gain of the 2SD438 will be in the range from 60 to 560, for the 2SD438-D it will be in the range from 60 to 120, for the 2SD438-E it will be in the range from 100 to 200, for the 2SD438-F it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SD438-G might only be marked "D438-G".The complementary PNP transistor to the 2SD438-G is the 2SB560-G.You can replace the 2SD438-G with the 2SC6043 or KTC1006.
