KSD1408O NPN Transistor

The KSD1408O is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the KSD1408O transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The KSD1408O 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 KSD1408O transistor as follows.
