TN2221AR NPN Transistor

The TN2221AR is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the TN2221AR transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The TN2221AR 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 TN2221AR transistor as follows.
