BTD1857AT3 NPN Transistor

The BTD1857AT3 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BTD1857AT3 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BTD1857AT3 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 BTD1857AT3 transistor as follows.
