Here is an image showing the pin diagram of this transistor.The 2SB761A-Q transistor can have a current gain of 70 to 150. The gain of the 2SB761A will be in the range from 40 to 250, for the 2SB761A-P it will be in the range from 120 to 250, for the 2SB761A-R it will be in the range from 40 to 90.Sometimes the "2S" prefix is not marked on the package - the 2SB761A-Q might only be marked "B761A-Q".The complementary NPN transistor to the 2SB761A-Q is the 2SD856A-Q.The BDP952 (SOT-223) is the SMD version of the 2SB761A-Q transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SB761A-Q with the 2N6475, 2N6476, 2N6491, 2N6491G, 2SA1010, 2SA1077, 2SA1293, 2SA1308, 2SA1329, 2SA1388, 2SA1452, 2SA1452A, 2SA1488A, 2SA1634, 2SA1635, 2SA1725, 2SA1726, 2SA769, 2SA771, 2SB1016, 2SB1016A, 2SB1017, 2SB1018, 2SB1018A, 2SB1090, 2SB1367, 2SB1368, 2SB1548A, 2SB1548A-Q, 2SB595, 2SB596, 2SB633, 2SB703, 2SB703A, 2SB708, 2SB747, 2SB762A, 2SB762A-Q, 2SB870, 2SB941A, 2SB941A-Q, 2SB942A, 2SB942A-Q, 2SB945, 2SB946, 2SB992, 2SB995, 2SB996, BD242B, BD242C, BD244B, BD244C, BD538, BD540B, BD540C, BD544B, BD544C, BD546B, BD546C, BD710, BD712, BD744B, BD744C, BD800, BD802, BD810, BD910, BD912, BD938, BD938F, BD940, BD940F, BD942, BD942F, BD952, BD954, BD956, BDT84, BDT84F, BDT86, BDT86F, BDT88, BDT88F, BDT94, BDT94F, BDT96, BDT96F, BDX78, D44C10, D44C11, D44C12, D45C10, D45C11, D45C12, D45H11, D45H11FP, KSA1010, KSB1017, KSB596, KSB708, KTA1038, KTA1049, KTB1367, KTB1368, MJE15029, MJE15029G, MJE15031, MJE15031G, MJF15031, MJF15031G, NTE153 or NTE292.
