Here is an image showing the pin diagram of this transistor.The 2SD863 transistor can have a current gain of 60 to 320. The gain of the 2SD863-D will be in the range from 60 to 120, for the 2SD863-E it will be in the range from 100 to 200, for the 2SD863-F it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SD863 might only be marked "D863".The complementary PNP transistor to the 2SD863 is the 2SB764.The 2SC3444 (SOT-89), FMMTA05 (SOT-23) and KST05 (SOT-23) is the SMD version of the 2SD863 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The KTD863 is the TO-92 version of the 2SD863.You can replace the 2SD863 with the 2SD667 or KTD863.
