BC438B NPN Transistor

The BC438B is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BC438B transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BC438B 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 BC438B transistor as follows.
