Here is an image showing the pin diagram of this transistor.The KTB1151 transistor can have a current gain of 160 to 400. The gain of the KTB1151-O will be in the range from 160 to 320, for the KTB1151-Y it will be in the range from 200 to 400.The complementary NPN transistor to the KTB1151 is the KTD1691.The 2STF2360 (SOT-89), 2STN2360 (SOT-223) and BDP950 (SOT-223) is the SMD version of the KTB1151 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTB1151 with the 2SB1151 or KSB1151.
