T2490 PNP Transistor

The T2490 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the T2490 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The T2490 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 T2490 transistor as follows.
