TK255A NPN Transistor

The TK255A is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the TK255A transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The TK255A 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 TK255A transistor as follows.
