Here are 4 simple 12V power supply circuits with output voltages around 12V. First power supply circuit is built with BD139, one zener diode and a few passive components. Each of the schematic is very ...

Discover how to build a simple device that converts light into electricity using LEDs and diodes. This step-by-step guide ...

Diodes whose reverse-breakdown characteristics are controlled precisely during manufacture are called as Zener diodes and are intended specifically for operation in the reverse breakdown mode ...

It isn’t unusual to expect a precisely regulated voltage in an electronic project, but what about times when you need a precise current? Over on EDN, prolific [Stephen Woodward] explains how to use a ...

Frederik Dostal explains the rise of the ideal diode and how it can be used to develop more robust power systems.

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