NB221ZI PNP Transistor

The NB221ZI is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the NB221ZI transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The NB221ZI 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 NB221ZI transistor as follows.
