2SB637K PNP Transistor

The 2SB637K is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the 2SB637K transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The 2SB637K 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 2SB637K transistor as follows.
