Voltage multiplier circuit forms a fundamental building block in high-voltage power supplies where the output voltage must be several times greater than the peak input voltage, yet the load current required is relatively small. Instead of using high-turn-ratio transformers which are large, expensive, and limited by insulation and core saturation constraints engineers often implement multipliers […]
Diodes
In this blog we will be discussing about different types of diode and symbol. A diode is basically two terminal electronic device which allows current to flow in one direction while it blocks the current in other direction.
It is made of two types of semiconductor materials namely p-type and n-type. By varying the properties of these materials different types of of diode are manufactured. Here are some different type of diodes described as follow.
Schottky diode
PN junction diode
Avalanche diode
Zener diode
Light Emitting Diode
Photodiode
Laser diode
Light Emitting Diode LED – Symbol, Construction, Working, Types and Applications
The Light Emitting Diode (LED) is one of the most widely used electronic components today, found in everything from indicator lights to full-scale lighting systems. It is a type of diode that converts electrical energy into light energy, offering a highly efficient alternative to traditional bulbs. Unlike incandescent lamps that rely on heating a filament, […]
Laser Diode – Symbol, Construction, Working, Types and Applications
A laser diode is a semiconductor device that emits coherent light through the process of stimulated emission. It operates similarly to a light-emitting diode (LED) but produces a focused, monochromatic, and coherent beam of light. The emitted light waves have the same wavelength, frequency, and phase. The laser diode was invented by Theodore H. Maiman, […]
Why Different Types of Diodes Are Used in Modern Circuit Design?
If you’ve ever opened up an electronic device – anything from a laptop charger to a pair of gaming headphones – you’ll notice tiny components scattered across the board. Among them, the diode is one of the most essential. It doesn’t look like much, but it plays a massive role in how circuits behave and […]
Photocoupler (Optocoupler / Optoisolator) – Construction, Working, Types & Applications
In modern electronics, signal isolation between different parts of a circuit is crucial for protection, noise reduction, and system stability. Optocouplers, also known as optoisolators, play a vital role in achieving this electrical isolation while allowing signal transmission. This article provides a thorough exploration of optocouplers (Optoisolator / Photocoupler), including their construction, working principles, advantages, […]
Seven Segment Display: Types, Working, Pin Diagram & Applications
We see numbers displayed on many electronic devices around us, like digital clocks, calculators, microwave ovens, and scoreboards. But have you ever wondered how these numbers appear on the screen? One of the most common ways to show numbers in electronic devices is by using a Seven Segment Display. It is a simple electronic component […]
