Here is an image showing the pin diagram of this transistor.The KTB988GR transistor can have a current gain of 150 to 300. The gain of the KTB988 will be in the range from 60 to 300, for the KTB988O it will be in the range from 60 to 120, for the KTB988Y it will be in the range from 100 to 200.The complementary NPN transistor to the KTB988GR is the KTD1351GR.The BDP950 (SOT-223) is the SMD version of the KTB988GR transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTB988GR with the 2SA1262, 2SA1488, 2SA1488A, 2SA1634, 2SA1635, 2SA1742, 2SA1742-L, 2SA1743, 2SA1743-L, 2SA1744, 2SA1744-L, 2SA770, 2SA771, 2SB1187, 2SB1375, 2SB1565, 2SB507, 2SB633, 2SB834, 2SB834GR, 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, KSB1366, KSB1366-G, KTA1036, KTA1036-GR, KTA1046GR, MJE15029 or MJE15029G.
