Here is an image showing the pin diagram of this transistor.The 2SB595 transistor can have a current gain of 40 to 240. The gain of the 2SB595-O will be in the range from 70 to 140, for the 2SB595-R it will be in the range from 40 to 80, for the 2SB595-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SB595 might only be marked "B595".The complementary NPN transistor to the 2SB595 is the 2SD525.The BDP954 (SOT-223) is the SMD version of the 2SB595 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SB595 with the 2SB1016, 2SB1367, 2SB995, BD244C, BD540C, BD802, BD954, BD956, BDT86, BDT86F, BDT88, BDT88F, KTB1367, MJE15029, MJE15029G, MJE15031, MJE15031G, MJF15031 or MJF15031G.
