SC257A PNP Transistor

The SC257A is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the SC257A transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The SC257A 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 SC257A transistor as follows.
