KSA1281 PNP Transistor

The KSA1281 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the KSA1281 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The KSA1281 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 KSA1281 transistor as follows.
