MMBTA42W NPN Transistor

The MMBTA42W is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the MMBTA42W transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The MMBTA42W 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 MMBTA42W transistor as follows.
