Here is an image showing the pin diagram of this transistor.The 2SB751A-P transistor can have a current gain of 4000 to 10000. The gain of the 2SB751A will be in the range from 1000 to 10000, for the 2SB751A-Q it will be in the range from 2000 to 5000, for the 2SB751A-R it will be in the range from 1000 to 2500.Sometimes the "2S" prefix is not marked on the package - the 2SB751A-P might only be marked "B751A-P".The complementary NPN transistor to the 2SB751A-P is the 2SD837A-P.You can replace the 2SB751A-P with the 2N6041, 2N6041G, 2N6042, 2N6042G, 2N6668, 2N6668G, 2SA1488A, 2SA771, 2SB1020, 2SB1020A, 2SB1024, 2SB1227, 2SB1228, 2SB1481, 2SB601, 2SB673, 2SB674, 2SB885, 2SB886, 2SB950A, 2SB950A-P, 2SB951A, 2SB951A-P, BD244B, BD244C, BD538, BD540B, BD540C, BD544B, BD544C, BD546B, BD546C, BD648, BD650, BD652, BD800, BD802, BD810, BD900, BD900A, BD902, BD952, BD954, BD956, BDT60A, BDT60B, BDT60C, BDT62A, BDT62B, BDT62C, BDT64A, BDT64B, BDT64C, BDT84, BDT84F, BDT86, BDT86F, BDT88, BDT88F, BDW24B, BDW24C, BDW46, BDW46G, BDW47, BDW47G, BDW48, BDW54B, BDW54C, BDW54D, BDW64B, BDW64C, BDW64D, BDW74B, BDW74C, BDW74D, BDX34B, BDX34BG, BDX34C, BDX34CG, BDX34D, BDX54B, BDX54BG, BDX54C, BDX54CG, BDX54D, BDX54E, BDX54F, BDX78, D44C10, D44C11, D44C12, D45C10, D45C11, D45C12, D45H11, D45H11FP, MJE15029, MJE15029G, MJE15031, MJE15031G, MJE702T, MJE703T, MJF127, MJF127G, MJF15031, MJF15031G, MJF6668, MJF6668G, TIP106, TIP106G, TIP107, TIP107G, TIP126, TIP126G, TIP127, TIP127G, TIP136, TIP136G, TIP137, TIP137G, TIP146T, TIP147T or TTB1020B.
