BF437 PNP Transistor

The BF437 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the BF437 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BF437 transistor symbol shows an arrow from the emitter into the base. This means that the current flows from emitter to collector terminal.

Circuit diagram symbol of the BF437 transistor as follows.
