The KTD1146Y 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 KTD1146Y transistor can have a current gain of 200 to 400. The gain of the KTD1146 will be in the range from 120 to 700, for the KTD1146GR it will be in the range from 350 to 700, for the KTD1146O it will be in the range from 120 to 240.
