T1903 PNP Transistor

The T1903 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the T1903 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The T1903 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 T1903 transistor as follows.
