MRF261 NPN Transistor

The MRF261 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the MRF261 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The MRF261 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 MRF261 transistor as follows.
