TIP74B PNP Transistor

The TIP74B is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the TIP74B transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The TIP74B 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 TIP74B transistor as follows.
