The KTC3205O 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.
Classification of hFE
The KTC3205O transistor can have a current gain of 100 to 200. The gain of the KTC3205 will be in the range from 100 to 320, for the KTC3205Y it will be in the range from 160 to 320.
Complementary PNP transistor
The complementary PNP transistor to the KTC3205O is the KTA1273O.
SMD Version of KTC3205O transistor
The KTC4375 (SOT-89) and KTC4375O (SOT-89) is the SMD version of the KTC3205O transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
