The KTC3205Y 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 KTC3205Y transistor can have a current gain of 160 to 320. The gain of the KTC3205 will be in the range from 100 to 320, for the KTC3205O it will be in the range from 100 to 200.The complementary PNP transistor to the KTC3205Y is the KTA1273Y.The KTC4375 (SOT-89) and KTC4375Y (SOT-89) is the SMD version of the KTC3205Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The 2SC3205-Y is the TO-92 version of the KTC3205Y.You can replace the KTC3205Y with the 2SC2328A, 2SC2328A-Y, 2SC2500, 2SC2500-A, 2SC2500-B, 2SC2500-C, 2SC2500-D, 2SC3205, 2SC3205-Y, 2SC4408, 2SC4604, 2SD1207, 2SD1347, 2SD1835, KSC2328A, KSC2328A-Y, KSC2500, KSC2500-A, KSC2500-B, KSC2500-C, KSC2500-D, KSC5019, KTC3210 or KTC3210Y.
