QST9 PNP Transistor

The QST9 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the QST9 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The QST9 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 QST9 transistor as follows.
