MM4021 PNP Transistor

The MM4021 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the MM4021 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The MM4021 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 MM4021 transistor as follows.
