T1657 PNP Transistor

The T1657 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the T1657 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The T1657 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 T1657 transistor as follows.
