PN4125 PNP Transistor

The PN4125 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the PN4125 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The PN4125 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 PN4125 transistor as follows.
