The 2N5814 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 collector, base, and emitter leads.
Here is an image showing the pin diagram of this transistor.The complementary PNP transistor to the 2N5814 is the 2N5815.The 2SC3912 (SOT-23), 2SC3913 (SOT-23), 2SC3914 (SOT-23), 2SC3915 (SOT-23) and MMBT4400 (SOT-23) is the SMD version of the 2N5814 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2N5814 with the 2N5820, BC485, BC485L, BC487, BC487L, BC489 or BC489L.
