BSR42 NPN Transistor

The BSR42 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BSR42 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BSR42 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 BSR42 transistor as follows.
