Here is an image showing the pin diagram of this transistor.The 2SB751A transistor can have a current gain of 1000 to 10000. The gain of the 2SB751A-P will be in the range from 4000 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 might only be marked "B751A".The complementary NPN transistor to the 2SB751A is the 2SD837A.You can replace the 2SB751A with the 2N6041, 2N6041G, 2N6042, 2N6042G, 2N6668, 2N6668G, 2SA1488A, 2SA771, 2SB1481, 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, MJF15031, MJF15031G, TIP106, TIP106G, TIP107, TIP107G, TIP126, TIP126G, TIP127, TIP127G, TIP136, TIP136G, TIP137, TIP137G, TIP146T or TIP147T.
