TN3903R NPN Transistor

The TN3903R is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the TN3903R transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The TN3903R 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 TN3903R transistor as follows.
