Here is an image showing the pin diagram of this transistor.The KSA1241 transistor can have a current gain of 70 to 240. The gain of the KSA1241-O will be in the range from 70 to 140, for the KSA1241-Y it will be in the range from 120 to 240.The complementary NPN transistor to the KSA1241 is the KSC3076.The 2SA1364 (SOT-89), BCP52 (SOT-223) and BCX52 (SOT-89) is the SMD version of the KSA1241 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KSA1241 with the 2SB1203, 2SB1204, KSA1244 or KTA1042L.
