Here is an image showing the pin diagram of this transistor.The 2SD1347S transistor can have a current gain of 140 to 280. 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 2SD1347T it will be in the range from 200 to 400, for the 2SD1347U it will be in the range from 280 to 560.Sometimes the "2S" prefix is not marked on the package - the 2SD1347S might only be marked "D1347S".The complementary PNP transistor to the 2SD1347S is the 2SB985S.The 2SD1623 (SOT-89), 2SD1623-S (SOT-89), 2SD1624 (SOT-89), 2SD1624-S (SOT-89) and BDP949 (SOT-223) is the SMD version of the 2SD1347S transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SD1347S with the 2SC4604.
