Here is an image showing the pin diagram of this transistor.The 2SD755-D transistor can have a current gain of 250 to 500. The gain of the 2SD755 will be in the range from 250 to 1200, 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-D might only be marked "D755-D".The complementary PNP transistor to the 2SD755-D is the 2SB715-D.The 2SC1622A (SOT-23) and FJV1845 (SOT-23) is the SMD version of the 2SD755-D transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SD755-D with the 2SC1841, 2SC1845, 2SC1890A, 2SC1890A-D, 2SC2240, 2SC2326, 2SC2326K, 2SC2363, 2SC2459, 2SC2544, 2SC2544-D, 2SC2547, 2SC2547-D, 2SC2784, 2SC3200, 2SC3201, 2SC3245, 2SC3245-F, 2SC3245A, 2SC3245A-F, 2SC3478, 2SD756, 2SD756-D, 2SD756A, 2SD756A-D, KSC1845 or KTC3200.
