637BCA NPN Transistor

The 637BCA is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the 637BCA transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The 637BCA 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 637BCA transistor as follows.
