The 2N6428 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 2SC1623 (SOT-23), 2SC2712 (SOT-23), 2SC4116 (SOT-323), 2SC4738 (SOT-23), FJX945 (SOT-323), KSC1623 (SOT-23), KTC3875 (SOT-23), KTC3875S (SOT-23) and PMBT6428 (SOT-23) is the SMD version of the 2N6428 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2N6428 with the KSP05, KSP06, MPS651, MPS651G, MPSA05, MPSA05G, MPSA06, MPSA06G, MPSW05, MPSW05G, MPSW06, MPSW06G or ZTX692B.
