The BC489 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 collector, base, and emitter leads.
Here is an image showing the pin diagram of this transistor.The BC489 transistor can have a current gain of 60 to 400. The gain of the BC489A will be in the range from 100 to 250, for the BC489B it will be in the range from 160 to 400, for the BC489L it will be in the range from 60 to 150.The complementary PNP transistor to the BC489 is the BC490.The FMMTA06 (SOT-23) and KST06 (SOT-23) is the SMD version of the BC489 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
