NB221E PNP Transistor

The NB221E is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the NB221E transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The NB221E 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 NB221E transistor as follows.
