This phenomenon in which current flows suddenly is called breakdown. Since a sudden increase in current occurs with a large voltage, breakdown in a typical diode can cause degradation or destruction of the element. Therefore, except for Zener diodes and ESD protection diodes that are intended to ...
Breakdown voltage is a property of an insulator or an electrically non-conductive material. Materials can be classified according to their resistivity or their ability to conduct electricity. Materials that freely conduct electricity are called conductors while materials that don't freely conduct electrici...
This level is known as the breakdown voltage. Above the breakdown region, even a small change in the voltage will cause a large change in the current. The forward bias and reverse bias properties of a semiconductor diode cause it to have an electrical conductivity value that's between the ...
Breakdown voltage is defined as a minimum voltage level at which the insulator starts behaving as a conductor and a large number of current passes through an insulator. The electrical properties of a diode lie between insulator and conductor because diodes are made up of semiconductor materials like...
Diode Breakdown Voltage Diodes are thesemiconductorsand their electrical properties lie in between that of conductors and insulators. APN junction diodeis formed using a P-type and N-type material. PN junction diodes contain a bandgap through which exchange of charge carriers takes place. When a fo...

An ESD protection diode is a type of Zener diode. When a diode is reverse-biased, little current flows from cathode to anode. However, when the reverse bias exceeds a certain point (called the reverse breakdown voltage), the reverse current suddenly increases. As the reverse bias ...
Because of the diode has the above characteristics, the circuit often used in the rectifier circuit, then the role of Zener diode is what? Let's take a look. Zener diode voltage regulator principle: Zener diode is the reverse voltage breakdown plus the breakdown, the voltage at both ends ...
Operational Principle of Zener Diode: In normal diodes, the breakdown voltage is very high and the diode gets damaged totally if a voltage above the breakdown diode is applied, but in Zener diodes, the breakdown voltage is not as high and does not lead to permanent damage of the zener diode...
A reverse bias type diode, it works using the avalanche effect. When voltage drop remains constant and is not affected by the current, the breakdown of avalanche takes place. These diodes are highly sensitive which makes them ideal for photo detection. ...
