The KTC3210 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 KTC3210 transistor can have a current gain of 100 to 320. The gain of the KTC3210O will be in the range from 100 to 200, for the KTC3210Y it will be in the range from 160 to 320.The complementary PNP transistor to the KTC3210 is the KTA1282.The KTC4375 (SOT-89) is the SMD version of the KTC3210 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTC3210 with the 2SC2328A, 2SC3205, 2SD1207, 2SD1347, 2SD1835, KSC2328A or KTC3205.
