BU109NP NPN Transistor

The BU109NP is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BU109NP transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BU109NP 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 BU109NP transistor as follows.
