MRF449A NPN Transistor

The MRF449A is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the MRF449A transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The MRF449A 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 MRF449A transistor as follows.
