BC161-25 PNP Transistor

The BC161-25 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the BC161-25 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BC161-25 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 BC161-25 transistor as follows.
