Here is an image showing the pin diagram of this transistor.The complementary NPN transistor to the 2N6555 is the 2N6552.The 2SA1368 (SOT-89), FMMTA56 (SOT-23) and KST56 (SOT-23) is the SMD version of the 2N6555 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2N6555 with the 2N6556.
