Here is an image showing the pin diagram of this transistor.The 2SD1347T transistor can have a current gain of 200 to 400. The gain of the 2SD1347 will be in the range from 100 to 560, for the 2SD1347R it will be in the range from 100 to 200, for the 2SD1347S it will be in the range from 140 to 280, for the 2SD1347U it will be in the range from 280 to 560.Sometimes the "2S" prefix is not marked on the package - the 2SD1347T might only be marked "D1347T".The complementary PNP transistor to the 2SD1347T is the 2SB985T.The 2SD1623 (SOT-89), 2SD1623-T (SOT-89), 2SD1624 (SOT-89), 2SD1624-T (SOT-89) and BDP949 (SOT-223) is the SMD version of the 2SD1347T transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SD1347T with the 2SC4604.
