Here is an image showing the pin diagram of this transistor.The 2SB761-P transistor can have a current gain of 120 to 250. The gain of the 2SB761 will be in the range from 40 to 250, for the 2SB761-Q it will be in the range from 70 to 150, for the 2SB761-R it will be in the range from 40 to 90.Sometimes the "2S" prefix is not marked on the package - the 2SB761-P might only be marked "B761-P".The complementary NPN transistor to the 2SB761-P is the 2SD856-P.The BDP950 (SOT-223) is the SMD version of the 2SB761-P transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SB761-P with the 2SA1262, 2SA1288, 2SA1289, 2SA1290, 2SA1291, 2SA1469, 2SA1470, 2SA1471, 2SA1488, 2SA1488A, 2SA1634, 2SA1635, 2SA1742, 2SA1743, 2SA1744, 2SA770, 2SA771, 2SB1133, 2SB1187, 2SB1274, 2SB1375, 2SB1548, 2SB1548-P, 2SB1548A, 2SB1548A-P, 2SB1565, 2SB507, 2SB633, 2SB761A, 2SB761A-P, 2SB762, 2SB762-P, 2SB762A, 2SB762A-P, 2SB834, 2SB858, 2SB870, 2SB941, 2SB941-P, 2SB941A, 2SB941A-P, 2SB942, 2SB942-P, 2SB942A, 2SB942A-P, 2SB943, 2SB944, 2SB945, 2SB946, BD204, BD242A, BD242B, BD242C, BD244A, BD244B, BD244C, BD304, BD536, BD538, BD540A, BD540B, BD540C, BD544A, BD544B, BD544C, BD546A, BD546B, BD546C, BD798, BD800, BD802, BD808, BD810, BD936, BD936F, BD938, BD938F, BD940, BD940F, BD942, BD942F, 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.
