TK31 PNP Transistor

The TK31 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the TK31 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The TK31 transistor symbol shows an arrow from the emitter into the base. This means that the current flows from emitter to collector terminal.

Circuit diagram symbol of the TK31 transistor as follows.
