AC142K PNP Transistor

The AC142K is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the AC142K transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The AC142K 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 AC142K transistor as follows.
