The STL128D is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the STL128D transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.
The STL128D 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 STL128D transistor as follows.
