H945Q NPN Transistor

The H945Q is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the H945Q transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The H945Q 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 H945Q transistor as follows.
