A diode is a tiny component with a powerful job—controlling the direction of electrical current. This video explains how ...

How does a varactor diode work? To form the PN junction that makes a diode, half the piece is doped with a trace amount of “donor atoms” that have one more electron than the intrinsic stuff to make ...

This video explains how LEDs (Light Emitting Diodes) function and why they are widely used in modern lighting and electronic displays. LEDs convert electrical energy into light through the movement of ...

The diode is one of the most commonly adopted and simply made elementary component in semiconductor technology. It’s been the basic starting brick for the construction of all electronic technology, ...
