Here is an image showing the pin diagram of this transistor.The 2SB546A-K transistor can have a current gain of 100 to 200. The gain of the 2SB546A will be in the range from 40 to 200, for the 2SB546A-L it will be in the range from 60 to 120, for the 2SB546A-M it will be in the range from 40 to 80.Sometimes the "2S" prefix is not marked on the package - the 2SB546A-K might only be marked "B546A-K".The complementary NPN transistor to the 2SB546A-K is the 2SD401A-K.The PBHV9115T (SOT-23), PBHV9115X (SOT-89), PBHV9115Z (SOT-223) and PBHV9215Z (SOT-223) is the SMD version of the 2SB546A-K transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SB546A-K with the 2SA1667, 2SA1668, 2SA1859, 2SA1859A, 2SA1930, 2SB546, 2SB547, 2SB630, 2SB630-Q, 2SB861, 2SB861C, 2SB940, 2SB940-P, 2SB940A, 2SB940A-P, KSB546, KTB1369, MJE15031, MJE15031G, MJE15033, MJE15033G, MJE5850, MJE5850G, MJF15031 or MJF15031G.
