BFQ18A NPN Transistor

The BFQ18A is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BFQ18A transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BFQ18A 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 BFQ18A transistor as follows.
