The KTC8050 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, base, and collector leads.
Here is an image showing the pin diagram of this transistor.The KTC8050 transistor can have a current gain of 100 to 300. The gain of the KTC8050C will be in the range from 100 to 200, for the KTC8050D it will be in the range from 150 to 300.The 2SC2859 (SOT-23), 2SC2883 (SOT-89), 2SC4118 (SOT-323), 2SC4210 (SOT-23), KTC3265 (SOT-23), KTC3876 (SOT-23), KTC3876S (SOT-23), KTC4376 (SOT-89) and KTC8050S (SOT-23) is the SMD version of the KTC8050 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTC8050 with the 2SD471A, BC537, MPS3704, MPS650, MPS650G, MPS651, MPS651G, MPS6602, MPS6602G, MPSW01, MPSW01A, MPSW01AG, MPSW01G, PN2219, PN2219A, PN2222A, ZTX449 or ZTX450.
