BF423A3 PNP Transistor

The BF423A3 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the BF423A3 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BF423A3 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 BF423A3 transistor as follows.
