MD2219A NPN Transistor

The MD2219A is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the MD2219A transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The MD2219A 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 MD2219A transistor as follows.
