MD1129F NPN Transistor

The MD1129F is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the MD1129F transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The MD1129F 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 MD1129F transistor as follows.
