ERS250 NPN Transistor

The ERS250 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the ERS250 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The ERS250 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 ERS250 transistor as follows.
