KSB1121 PNP Transistor

The KSB1121 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the KSB1121 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The KSB1121 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 KSB1121 transistor as follows.
