SFT445 NPN Transistor

The SFT445 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the SFT445 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The SFT445 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 SFT445 transistor as follows.
