To measure a zener diode’s breakdown voltage, you need a dc voltage source whose voltage exceeds that of the zener voltage. In Figure 1, resistor R SER provides voltage drop between V IN and V ZEN. In ...

Since the earliest versions of indoor LED light bulbs were developed, their designers have faced a variety of technical challenges. These include AC-to-DC power conversion, thermal design/heat-sinking ...

The polarity markings on LEDs (Light Emitting Diodes) seem to be a common cause of confusion. The polarity may be indicated by a flat section on one side of the body or by one lead being shorter than ...

Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...

This file type includes high resolution graphics and schematics. LEDs are the most efficient way to turn an electric current into illumination. When a current flows through a diode in the forward ...

Reverse polarity is one of the most common causes of circuit failure, from hobby projects to industrial systems. The good news is that a well-designed reverse polarity protection using MOSFET ...

Discover how to build a simple device that converts light into electricity using LEDs and diodes. This step-by-step guide demonstrates assembling an LED-diode cluster, connecting it to a capacitor for ...

[Hales] has been on a mission for a while to make his own diodes and put them to use and now he’s succeeded with diodes made of sodium bicarbonate and water, aluminum tape and soldered copper. By ...

A diode is a semiconductor device that allows electrical current to flow in one direction while blocking it in the other.
