E7142 PNP Transistor

The E7142 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the E7142 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The E7142 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 E7142 transistor as follows.
