Here is an image showing the pin diagram of this transistor.The KTD863-O transistor can have a current gain of 60 to 120. The gain of the KTD863 will be in the range from 60 to 320, for the KTD863-GR it will be in the range from 160 to 320, for the KTD863-Y it will be in the range from 100 to 200.The 2SC3444 (SOT-89), 2SC3444-C (SOT-89), BCP55 (SOT-223), BSR40 (SOT-89), FMMTA05 (SOT-23) and KST05 (SOT-23) is the SMD version of the KTD863-O transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The 2SD863-D is the TO-92 version of the KTD863-O.You can replace the KTD863-O with the 2SC3243, 2SD667, 2SD667A, 2SD667AB, 2SD667B, 2SD863 or 2SD863-D.
