D12E109 NPN Transistor

The D12E109 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the D12E109 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The D12E109 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 D12E109 transistor as follows.
