MP2145A PNP Transistor

The MP2145A is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the MP2145A transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The MP2145A transistor symbol shows an arrow from the emitter into the base. This means that the current flows from emitter to collector terminal.

Circuit diagram symbol of the MP2145A transistor as follows.
