TK70A NPN Transistor

The TK70A is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the TK70A transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The TK70A 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 TK70A transistor as follows.
