D31B PNP Transistor

The D31B is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the D31B transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The D31B 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 D31B transistor as follows.
