The BF253-3 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BF253-3 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.
The BF253-3 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 BF253-3 transistor as follows.
