Here is an image showing the pin diagram of this transistor.The KTA1277Y transistor can have a current gain of 100 to 200. The gain of the KTA1277 will be in the range from 60 to 200, for the KTA1277O 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 KTA1277Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTA1277Y with the 2SA1625, 2SA1625-K, KSA1625 or KSA1625-K.
