The 2N4901SMD is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the 2N4901SMD transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.
The 2N4901SMD transistor symbol shows an arrow from the emitter into the base. This means that the current flows from emitter to collector terminal.
