QST4 PNP Transistor

The QST4 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the QST4 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The QST4 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 QST4 transistor as follows.
