BC437A NPN Transistor

The BC437A is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BC437A transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BC437A 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 BC437A transistor as follows.
