Due to the flow of reverse current the width of the junction barrier increases. When this applied reverse bias voltage is increased gradually at a certain point a rapid increase in the reverse current can be observed. This is known as Junction breakdown. The corresponding applied reverse voltage ...
In general, all the electronic devices need DC power supply but it is impossible to generate DC power so, we need an alternative to get some DC power thus the usage of diodes comes into the pictureto convert AC power to DC power. A diode is a tiny electronic component used in almost a...
A Zener diode is a type of pn junction diode. Zener diodes are used in the breakdown region (yield region) by applying a voltage in the opposite direction to normal pn junction diodes.
In summary, the formation of a Pn junction in a semiconductor creates a depletion region where there are no free charge carriers, only ions. This forms a barrier potential with a negative terminal on the P side and a positive terminal on the N side. In order for a diode to conduct ...
only drawback of these diodes. avalanche diode this diode belongs to a reverse bias type and operates using the avalanche effect. when voltage drop is constant and is independent of current, the breakdown of avalanche takes place. they exhibit high levels of sensitivity and hence are used for ...
The main characteristics of the diode is unidirectional conductivity, that is, under the action of t
Typically, a diode does not conduct when it is reverse-biased. However, as reverse-bias voltage is increased, large current suddenly passes through a diode at a given voltage. This voltage is called breakdown voltage (VBR). In the breakdown region above VBR, a slight change in voltage causes...
Your life is organized like an orbit. I know. 了解了这点,就知道为何四年于相隔千里的我们,似乎只是弹指一挥间而已。 我其实了解小女儿的心理,是希望多一点surprise多一点romantic多一点傻里吧唧的指天划地的。可惜我这方面的才能似乎多用在0,1组成的无机世界里了,于是只能委屈她了。大多数的时间,她就一...
A Zener diode is a type of pn junction diode. Zener diodes are used in the breakdown region (yield region) by applying a voltage in the opposite direction to normal pn junction diodes.
Zener Effect is the category of the electric failure (breakdown) that exits in reverse biasing PN junction the strong statice field allows the electrons to move from the valance band to the conductive band of a semiconductor. Its name is due to the use of this factor in the operation of th...
