MMBTA45 NPN Transistor

The MMBTA45 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the MMBTA45 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The MMBTA45 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 MMBTA45 transistor as follows.
