BC420A PNP Transistor

The BC420A is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the BC420A transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BC420A 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 BC420A transistor as follows.
