Here is an image showing the pin diagram of this transistor.The 2SB546A-M transistor can have a current gain of 40 to 80. The gain of the 2SB546A will be in the range from 40 to 200, for the 2SB546A-K it will be in the range from 100 to 200, for the 2SB546A-L it will be in the range from 60 to 120.Sometimes the "2S" prefix is not marked on the package - the 2SB546A-M might only be marked "B546A-M".The complementary NPN transistor to the 2SB546A-M is the 2SD401A-M.You can replace the 2SB546A-M with the 2SB546, 2SB546-R, 2SB547, 2SB630, 2SB630-S, KSB546, KSB546-R, MJE15031, MJE15031G, MJE5172, MJE5850, MJE5850G, MJF15031 or MJF15031G.
