Here is an image showing the pin diagram of this transistor.The 2SB1133-S transistor can have a current gain of 140 to 280. The gain of the 2SB1133 will be in the range from 70 to 280, for the 2SB1133-Q it will be in the range from 70 to 140, for the 2SB1133-R it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SB1133-S might only be marked "B1133-S".The complementary NPN transistor to the 2SB1133-S is the 2SD1666-S.The BDP950 (SOT-223) is the SMD version of the 2SB1133-S transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SB1133-S with the 2SA1262, 2SA1288, 2SA1288-S, 2SA1289, 2SA1289-S, 2SA1290, 2SA1290-S, 2SA1291, 2SA1291-S, 2SA1469, 2SA1469-S, 2SA1470, 2SA1470-S, 2SA1471, 2SA1471-S, 2SA1488, 2SA1488A, 2SA1634, 2SA1635, 2SA1742, 2SA1743, 2SA1744, 2SA770, 2SA771, 2SB1187, 2SB1274, 2SB1274S, 2SB1375, 2SB1565, 2SB507, 2SB633, 2SB834, 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, KTA1036, KTB988, MJE15029 or MJE15029G.
