BLW81 NPN Transistor

The BLW81 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BLW81 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BLW81 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 BLW81 transistor as follows.
