Here is an image showing the pin diagram of this transistor.The 2SB950-Q transistor can have a current gain of 2000 to 5000. The gain of the 2SB950 will be in the range from 2000 to 10000, for the 2SB950-P it will be in the range from 4000 to 10000.Sometimes the "2S" prefix is not marked on the package - the 2SB950-Q might only be marked "B950-Q".The complementary NPN transistor to the 2SB950-Q is the 2SD1276-Q.You can replace the 2SB950-Q with the 2N6040, 2N6040G, 2N6041, 2N6041G, 2N6042, 2N6042G, 2N6667, 2N6667G, 2N6668, 2N6668G, 2SA1259, 2SA1262, 2SA1488, 2SA1488A, 2SA770, 2SA771, 2SB1020, 2SB1020A, 2SB1024, 2SB1223, 2SB1224, 2SB1225, 2SB1227, 2SB1228, 2SB1481, 2SB601, 2SB601-M, 2SB673, 2SB674, 2SB675, 2SB751, 2SB751-Q, 2SB751A, 2SB751A-Q, 2SB880, 2SB881, 2SB882, 2SB885, 2SB886, 2SB950A, 2SB950A-Q, 2SB951, 2SB951-Q, 2SB951A, 2SB951A-Q, BD204, BD244A, BD244B, BD244C, BD304, BD536, BD538, BD540A, BD540B, BD540C, BD544A, BD544B, BD544C, BD546A, BD546B, BD546C, BD646, BD648, BD650, BD652, BD798, BD800, BD802, BD808, BD810, BD898, BD898A, BD900, BD900A, BD902, BD950, BD952, BD954, BD956, BDT60, BDT60A, BDT60B, BDT60C, BDT62, BDT62A, BDT62B, BDT62C, BDT64, BDT64A, BDT64B, BDT64C, BDT82, BDT82F, BDT84, BDT84F, BDT86, BDT86F, BDT88, BDT88F, BDW24A, BDW24B, BDW24C, BDW45, BDW46, BDW46G, BDW47, BDW47G, BDW48, BDW54A, BDW54B, BDW54C, BDW54D, BDW64A, BDW64B, BDW64C, BDW64D, BDW74A, BDW74B, BDW74C, BDW74D, BDX34A, BDX34B, BDX34BG, BDX34C, BDX34CG, BDX34D, BDX54A, BDX54B, BDX54BG, BDX54C, BDX54CG, BDX54D, BDX78, D44C10, D44C11, D44C12, D44C7, D44C8, D44C9, D45C10, D45C11, D45C12, D45C7, D45C8, D45C9, D45H11, D45H11FP, D45H8, MJE15029, MJE15029G, MJE700T, MJE701T, MJE702T, MJE703T, MJF127, MJF127G, TIP105, TIP105G, TIP106, TIP106G, TIP107, TIP107G, TIP125, TIP125G, TIP126, TIP126G, TIP127, TIP127G, TIP135, TIP135G, TIP136, TIP136G, TIP137, TIP137G, TIP145T, TIP146T, TIP147T or TTB1020B.
