MMBT5857 PNP Transistor

The MMBT5857 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the MMBT5857 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The MMBT5857 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 MMBT5857 transistor as follows.
