Why is silicon preferred over germanium when producing diodes?

Silicon crystals have less free electrons than germanium crystals. However, silicon crystals can not easily be damaged by excessive heat. Peak inverse voltage ratings of silicon diodes are larger than germanium diodes. Si is less expensive due to the larger…

What is the diode rectifier app?

Diode rectifier app Apart from normal dc supplies, they can be used as current sources, as indirect voltage measurements, for reading line frequencies, for frequency doubling¬† non sinusoidal waveform such as triangles, squares, rectangles. To understand the diode rectifier application,…

Can an LED be used instead of a diode (because basically both are diodes)?

Led has low current rating. The safe operating forward current is something like 30-40 ma. this is too small for a rectifier application. The practical load rectifier draws more current which also varies the current. The second point is Led…

Why is diode useful?

The diode is useful because of its directional behavior, which allows forward flow of current and blocking in the opposite direction.The unidirectional property of this diode is useful for converting ac to dc called as rectification. A reason for this…

Under what conditions will a diode be turned on? Explain

As we all know, generally the diodes are two terminals of uni-directional semiconductor devices. The diode is just an electronic switch! depending on the voltage difference between the terminals we can utilize the diode function. the starting diode only performs…

What is Zener Diode? What are the uses?

What is Zener Diode. Zener diode is a special type of diode whose reverse bias voltage discharge is an interesting characteristic. a steeply penetrating voltage with a current thereby making the voltage reference point somewhat stable when fed with a…

Why do we use diodes in series?

we use diodes in series The basic purpose of diode is limiting direction of current. As we all know the current flow will be from + ve terminal to the -ve terminal. but during the ac current case, the polarity…

Why diode is called a valve?

diode is called a valve The diode passes the current in one direction (anode to the cathode), and blocks the current in the opposite direction (cathode to anode). so it is used in reverse voltage protection circuitry and mostly in…
