CD1899 NPN Transistor

The CD1899 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the CD1899 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The CD1899 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 CD1899 transistor as follows.
