The 2N5401C 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. Suffix "C" means center collector in 2N5401.
Here is an image showing the pin diagram of this transistor.The complementary NPN transistor to the 2N5401C is the 2N5551C.The 2N5401S (SOT-23), DXT5401 (SOT-89), DZT5401 (SOT-223), KST5401 (SOT-23), MMBT5401 (SOT-23) and PMBT5401 (SOT-23) is the SMD version of the 2N5401C transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2N5401C with the 2SA1275, KSA1013 or KTA1275.
