Here is an image showing the pin diagram of this transistor.The KSB1017 transistor can have a current gain of 40 to 240. The gain of the KSB1017-O will be in the range from 70 to 140, for the KSB1017-R it will be in the range from 40 to 80, for the KSB1017-Y it will be in the range from 120 to 240.The complementary NPN transistor to the KSB1017 is the KSD1408.The BDP952 (SOT-223) is the SMD version of the KSB1017 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KSB1017 with the 2SA1488A, 2SA771, 2SB1016, 2SB1017, 2SB1367, 2SB1368, 2SB595, 2SB596, 2SB633, 2SB762A, 2SB942A, 2SB995, 2SB996, BD244B, BD244C, BD538, BD540B, BD540C, BD800, BD802, BD810, BD952, BD954, BD956, BDT84, BDT84F, BDT86, BDT86F, BDT88, BDT88F, BDX78, D44C10, D44C11, D44C12, D45C10, D45C11, D45C12, KSB596, KTB1367, KTB1368, MJE15029, MJE15029G, MJE15031, MJE15031G, MJF15031 or MJF15031G.
