Here is an image showing the pin diagram of this transistor.The 2SD755 transistor can have a current gain of 250 to 1200. The gain of the 2SD755-D will be in the range from 250 to 500, for the 2SD755-E it will be in the range from 400 to 800, for the 2SD755-F it will be in the range from 600 to 1200.Sometimes the "2S" prefix is not marked on the package - the 2SD755 might only be marked "D755".The complementary PNP transistor to the 2SD755 is the 2SB715.The FJV1845 (SOT-23) is the SMD version of the 2SD755 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SD755 with the 2SC1841, 2SC1845, 2SC1890A, 2SC2544, 2SC2784 or KSC1845.
