The 2SA1625-K is manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right, the emitter, collector, and base leads.
Here is an image showing the pin diagram of this transistor.The 2SA1625-K transistor can have a current gain of 100 to 200. The gain of the 2SA1625 will be in the range from 40 to 200, for the 2SA1625-L it will be in the range from 60 to 120, for the 2SA1625-M it will be in the range from 40 to 80.Sometimes the "2S" prefix is not marked on the package - the 2SA1625-K might only be marked "A1625-K".The PBHV9040T (SOT-23), PBHV9040X (SOT-89), PBHV9040Z (SOT-223) and STR2550 (SOT-23) is the SMD version of the 2SA1625-K transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The KSA1625-K is the TO-92 version of the 2SA1625-K.You can replace the 2SA1625-K with the KSA1625, KSA1625-K, KTA1277 or KTA1277Y.
