PN4257 NPN Transistor

The PN4257 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the PN4257 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The PN4257 transistor symbol shows an arrow from the base into the emitter. This means that the current flows from collector terminal to emitter terminal.

Circuit diagram symbol of the PN4257 transistor as follows.
