The KTC3203O 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 KTC3203O transistor can have a current gain of 100 to 200. The gain of the KTC3203 will be in the range from 100 to 320, for the KTC3203Y it will be in the range from 160 to 320.The complementary PNP transistor to the KTC3203O is the KTA1271O.The 2SC2859 (SOT-23), 2SC2883 (SOT-89), 2SC2883-O (SOT-89), 2SC4118 (SOT-323), 2SC4210 (SOT-23), 2SC4210-O (SOT-23), KSC2859 (SOT-23), KTC3265 (SOT-23), KTC3265-O (SOT-23), KTC3876 (SOT-23), KTC3876S (SOT-23), KTC4376 (SOT-89), KTC4376O (SOT-89), KTC8050S (SOT-23) and KTC8050S-C (SOT-23) is the SMD version of the KTC3203O transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The 2SC3203-O is the TO-92 version of the KTC3203O.You can replace the KTC3203O with the 2SC1384, 2SC2120, 2SC2120-O, 2SC2236, 2SC2236-O, 2SC2328A, 2SC2328A-O, 2SC2655, 2SC2710, 2SC2710-O, 2SC3203, 2SC3203-O, 2SC3205, 2SC3205-O, 2SC3243, 2SC3940A, 2SD1207, 2SD1207-R, 2SD1347, 2SD1347R, 2SD1835, 2SD1835-R, 2SD789, 2SD789-B, 2SD863, 2SD863-E, KSC2328A, KSC2328A-O, KTC1008, KTC1008-Y, KTC3204, KTC3204O, KTC3205, KTC3205O, KTC3209, KTC3210, KTC3210O, KTD863 or KTD863-Y.Same transistor is also available in:
