AC187-9 NPN Transistor

The AC187-9 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the AC187-9 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The AC187-9 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 AC187-9 transistor as follows.
