FT45 NPN Transistor

The FT45 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the FT45 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The FT45 transistor symbol shows an arrow from the base into the emitter. This means that the current flows from collector terminal to emitter terminal.

Circuit diagram symbol of the FT45 transistor as follows.
