The KTC3204Y 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 KTC3204Y transistor can have a current gain of 160 to 320. The gain of the KTC3204 will be in the range from 100 to 320, for the KTC3204O it will be in the range from 100 to 200.The complementary PNP transistor to the KTC3204Y is the KTA1272Y.The 2SC2859 (SOT-23), 2SC2883 (SOT-89), 2SC2883-Y (SOT-89), 2SC4118 (SOT-323), 2SC4210 (SOT-23), 2SC4210-Y (SOT-23), KTC3265 (SOT-23), KTC3265-Y (SOT-23), KTC3876 (SOT-23), KTC3876S (SOT-23), KTC4376 (SOT-89), KTC4376Y (SOT-89), KTC8050S (SOT-23) and KTC8050S-D (SOT-23) is the SMD version of the KTC3204Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTC3204Y with the 2SC1384, 2SC2120, 2SC2120-Y, 2SC2236, 2SC2236-Y, 2SC2328A, 2SC2328A-Y, 2SC2500, 2SC2500-A, 2SC2500-B, 2SC2500-C, 2SC2500-D, 2SC2710, 2SC2710-Y, 2SC3203, 2SC3203-Y, 2SC3205, 2SC3205-Y, 2SC3940A, 2SC4408, 2SC4604, 2SD1207, 2SD1347, 2SD1616, 2SD1616A, 2SD1835, 2SD789, 2SD789-C, 2SD863, 2SD863-F, KSC2328A, KSC2328A-Y, KSC2500, KSC2500-A, KSC2500-B, KSC2500-C, KSC2500-D, KSC5019, KSD1021, KSD1616, KSD1616A, KSD471AC, KTC1008, KTC1008-GR, KTC3203, KTC3203Y, KTC3205, KTC3205Y, KTC3210, KTC3210Y, KTD863 or KTD863-GR.
