Here is an image showing the pin diagram of this transistor.The KTA1703-Y transistor can have a current gain of 100 to 200. The gain of the KTA1703 will be in the range from 60 to 200, for the KTA1703-O it will be in the range from 60 to 120.The PBHV9040T (SOT-23), PBHV9040X (SOT-89), PBHV9040Z (SOT-223) and STR2550 (SOT-23) is the SMD version of the KTA1703-Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTA1703-Y with the 2SA1156, 2SA1156K, KSA1156 or KSA1156Y.
