121-1019 PNP Transistor

The 121-1019 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the 121-1019 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The 121-1019 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 121-1019 transistor as follows.
