The UML4N is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the UML4N transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.
The UML4N 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 UML4N transistor as follows.
