NB221YI PNP Transistor

The NB221YI is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the NB221YI transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The NB221YI 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 NB221YI transistor as follows.
