D28B NPN Transistor

The D28B is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the D28B transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The D28B 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 D28B transistor as follows.
