CS1978A NPN Transistor

The CS1978A is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the CS1978A transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The CS1978A 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 CS1978A transistor as follows.
