TK203A NPN Transistor

The TK203A is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the TK203A transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The TK203A 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 TK203A transistor as follows.
