BD678H PNP Transistor

The BD678H is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the BD678H transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BD678H 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 BD678H transistor as follows.
