Here is an image showing the pin diagram of this transistor.The KSB546 transistor can have a current gain of 40 to 240. The gain of the KSB546-O will be in the range from 70 to 140, for the KSB546-R it will be in the range from 40 to 80, for the KSB546-Y it will be in the range from 120 to 240.The complementary NPN transistor to the KSB546 is the KSD401.You can replace the KSB546 with the 2SB546, 2SB547, MJE15031, MJE15031G, MJE5850, MJE5850G, MJF15031 or MJF15031G.
