Here is an image showing the pin diagram of this transistor.The 2SD1347U transistor can have a current gain of 280 to 560. 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 2SD1347T it will be in the range from 200 to 400.Sometimes the "2S" prefix is not marked on the package - the 2SD1347U might only be marked "D1347U".The complementary PNP transistor to the 2SD1347U is the 2SB985U.The 2SD1623 (SOT-89), 2SD1623-U (SOT-89), 2SD1624 (SOT-89) and 2SD1624-U (SOT-89) is the SMD version of the 2SD1347U transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
