BD664B PNP Transistor

The BD664B is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the BD664B transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BD664B 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 BD664B transistor as follows.
