Pinout of PN918

The PN918 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.

SMD Version of PN918 transistor

The MMBT918 (SOT-23) is the SMD version of the PN918 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.

PN918 Transistor in TO-92 Package

The MPS918 is the TO-92 version of the PN918.
