In this article we will learn about the main application of diode. we will discuss about the specification and temperature base application of diode. following application of diode given below.
Application of Diode
1. Diodes are used in communication receivers for modulation
and demodulation.
2. It is used as a switch in high speed digital circuit.
3. Diodes are used in rectifiers. In low power and high
power rectification process.
4. With the use of diodes, we can form complex circuit diodes,
varactor diodes, gunn diodes.
It is the some application of diode.
It is the some application of diode.
Specification of diode
For knowing more about application of we need to know about the specification of diode.
Some of the specifications of the diode which are considered
during manufacturing are as given below.
1. Semiconductor material
We know that diode is made of doped semiconductor material.
This could be silicon or germanium. The material used in the p-n junction diode
of great importance because cut-in-voltage or knee voltage depends upon the
material of the diode. The material used also affects many of the major diode characteristic
and properties.
2. Peak inverse Voltage (PIV)
The maximum voltage of a diode can withstand in the reverse
direction is called the peak inverse voltage. This voltage must not be exceeded
otherwise the device may be fail.
3. Forward Voltage drop
It is the voltage drop which appears across the diode when
the maximum average current flows through it continuously.
4. Maximum forward current
It is the maximum current that a diode can allow to flow through
it without getting demaed.
5. Maximum revers current
It is the maximum current that can flow through the diode
when the maximum reverse voltage or PIV is applied.
6. Maximum Forward surge current
It is the forward current that can flow through the diode
for a defined short period of time.
7. Maximum junction Temperature
It is the maximum temperature that a diode junction can
withstand without getting damaged.
Some other application of diode
1. Diode use as rectifier. it is used in rectifier circuit for convert AC power into DC power .
2. It is use as a amplifier .
3. its maximum used DC circuit or control circuit.
Temperature Effect on diode
The application of diode is also depend on temperature effect
on diode. The temperature has the following effects on the diode parameters.
1. The cut in voltage decrease as the temperature increases.
2. the reverse saturation current ( the current in case of
reverse biasing of diode) increases as the temperature increases.
3. Reverse breakdown voltage is increased with increase in
temperature.
If temperature is increased, the more number of electron –hole
pairs are produced in the p-n junction diode. This results in increasing the current
through the diode and the knee voltage is reduced.
Example
Considered a p-n junction diode of silicon having knee
voltage is 0.7V at 0 degree. If the
temperature is increased, the value of knee voltage is decreased as shown graph
given below.
