Here is an image showing the pin diagram of this transistor.The 2SB731-E transistor can have a current gain of 360 to 600. The gain of the 2SB731 will be in the range from 135 to 600, for the 2SB731-F it will be in the range from 300 to 480, for the 2SB731-K it will be in the range from 200 to 400, for the 2SB731-L it will be in the range from 135 to 270.Sometimes the "2S" prefix is not marked on the package - the 2SB731-E might only be marked "B731-E".The 2SB1115 (SOT-89), 2SB1115-YK (SOT-89), 2SB1122 (SOT-89), 2SB1122-U (SOT-89), 2STR2160 (SOT-23), FMMTA55 (SOT-23), KST55 (SOT-23), MMBTA55 (SOT-23), PZTA55 (SOT-223) and SMBTA55 (SOT-23) is the SMD version of the 2SB731-E transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SB731-E with the BD168, BD170, BD190, BD236, BD236G, BD238, BD238G, MJE235, MJE252, MJE254, MJE711 or MJE712.
