T1891 NPN Transistor

The T1891 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the T1891 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The T1891 transistor symbol shows an arrow from the base into the emitter. This means that the current flows from collector terminal to emitter terminal.

Circuit diagram symbol of the T1891 transistor as follows.
