LBC557B PNP Transistor

The LBC557B is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the LBC557B transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The LBC557B 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 LBC557B transistor as follows.
