KSD1021 NPN Transistor

The KSD1021 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the KSD1021 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The KSD1021 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 KSD1021 transistor as follows.
