BCY57 NPN Transistor

The BCY57 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BCY57 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BCY57 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 BCY57 transistor as follows.
