Here is an image showing the pin diagram of this transistor.Sometimes the "2S" prefix is not marked on the package - the 2SB547 might only be marked "B547".The complementary NPN transistor to the 2SB547 is the 2SD402.The PBHV9115T (SOT-23), PBHV9115X (SOT-89), PBHV9115Z (SOT-223) and PBHV9215Z (SOT-223) is the SMD version of the 2SB547 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SB547 with the 2SA1667, 2SA1668, 2SA1859, 2SA1859A, 2SA1930, 2SB546, 2SB546-O, 2SB546-R, 2SB546-Y, 2SB546A, 2SB546A-K, 2SB546A-L, 2SB546A-M, 2SB630, 2SB630-Q, 2SB630-R, 2SB630-S, 2SB861, 2SB861B, 2SB861C, 2SB940, 2SB940-P, 2SB940-Q, 2SB940A, 2SB940A-P, 2SB940A-Q, BDX54F, FJP1943, FJP1943O, FJP1943R, FJPF1943, FJPF1943O, FJPF1943R, KSB546, KSB546-O, KSB546-R, KSB546-Y, KTB1369, KTB1369O, KTB1369Y, MJE15031, MJE15031G, MJE15033, MJE15033G, MJF15031, MJF15031G or NTE398.
