TI490 NPN Transistor

The TI490 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the TI490 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The TI490 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 TI490 transistor as follows.
