BT3999 PNP Transistor

The BT3999 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the BT3999 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BT3999 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 BT3999 transistor as follows.
