Here is an image showing the pin diagram of this transistor.The KSB1366 transistor can have a current gain of 100 to 320. The gain of the KSB1366-G will be in the range from 150 to 320, for the KSB1366-Y it will be in the range from 100 to 200.The complementary NPN transistor to the KSB1366 is the KSD2012.The BDP950 (SOT-223) is the SMD version of the KSB1366 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KSB1366 with the 2SA1262, 2SA1488, 2SA1488A, 2SA1634, 2SA1635, 2SA1742, 2SA1743, 2SA1744, 2SA770, 2SA771, 2SB1187, 2SB1375, 2SB1565, 2SB507, 2SB633, 2SB858, BD204, BD242A, BD242B, BD242C, BD244A, BD244B, BD244C, BD304, BD536, BD538, BD540A, BD540B, BD540C, BD544A, BD544B, BD544C, BD546A, BD546B, BD546C, BD798, BD800, BD802, BD808, BD810, BD950, BD952, BD954, BD956, BDT82, BDT82F, BDT84, BDT84F, BDT86, BDT86F, BDT88, BDT88F, BDX78, D44C10, D44C11, D44C12, D44C7, D44C8, D44C9, D45C10, D45C11, D45C12, D45C7, D45C8, D45C9, D45H11, D45H11FP, D45H8, MJE15029 or MJE15029G.
