MM4546 PNP Transistor

The MM4546 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the MM4546 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The MM4546 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 MM4546 transistor as follows.
