Why not gate is not possible using diodes?
Diodes cannot invert, a required part of the not operation.
Difference between power diode and simple diode?
Major Differences1- DesignSimple diodes consist of a simple PN junction. They are smaller in size and lighter in weight, while power diodes are in modified form and they are larger and heavier normally. Power diodes are usually available in metal form.2- Voltage RatingSimple diodes are used in normal low power components so they have a relatively low voltage ratings as compared to power diodes. Power diodes can have very high voltage ratings usually in thousands of volts.3- Current RatingPower diodes have a high hand in Current ratings over normal diodes , that can be in several hundred amperes.4-TemperatureMajor probelm in handling high power applications is the generation of heat and temperature. Power diodes have the accessiblity of operation at higher temperature whereas normal diodes do not need this feature in high priority.5- CostPower Diodes are costly as compared to the simple diodes due to the additional components and features.
What are the advantages of Trapatt diodes over Impatt diodes?
Advantages of Trapatt:• higher efficiency than impatt• very low power dissipationAdvantages of Impatt:• This microwave diode has high power capability compare to other diodes.• Output is reliable compare to other diodes.
What are the Applications of Diodes?
These diodes are used in a variety of applications from low power radar systems to alarms. A major drawback of using IMPATT diodes is the high level of phase noise they generate. This results from the statistical nature of the avalanche process. Nevertheless these diodes make excellent microwave generators for many applications. A main advantage is their high power capability. They operate at frequencies between about 3 and 100 GHz or more. http://artizle.blogspot.com
What are the classifications of diodes?
a diode is a device that alows current to flow in one direction you have power diodes which are used in rectification processes and high current operations but the two main families of diodes are solid state diodes or valve operated diodes.
What are the differences between power diode and signal diode?
Simple diode is a two-terminal pn-junction with appropriate contacts for connecting the junction to external circuits. Power diode is formed by alloying, diffusion, and epitaxial growth. The modern techniques in semiconductor fabrication processes permit the desired device characteristics. The operation of power diodes is similar to that of signal diodes; but it has larger power-, voltage-, and current-handling capabilities than those of ordinary diodes. Switching speed of the power diodes is low compared to that of signal diodes.
Is it possible to design a transistor by using two diodes practically?
No.
What are the applications of IMPATT diode?

What type of diodes are used in bridge rectifier?
Mainly diodes that handle a fair amount of power. When diodes are constructed in a "bridge", it usually means someone is trying to rectify AC to DC voltage in what is considered a "full wave". Both sides of the sine wave + and - are utilized to change the AC current into DC. Typically power diodes are used in this fashion. Crystal diodes or other types will not work in a bridge circuit as they cannot handle the amperage or wattage that typically is wanted. Power diodes are usually ones that handle 1 amp or more of current. Some power diodes can handle 60 amps or more if properly constructed in a heat sink dependent upon their ratings.
Are diodes often used as switches?
Diodes perform a different function as switches. switches allow you to control wether or ot electricity is flowing. diodes only allow power to flow in one direction. A light emitting diode may be used as an indicator for wether or not power is flowing through a circuit.
Because solid state diodes have no filament?
require less operating power
What is difference between power diode and ordinary diode?
the High voltage rated diodes are power diodes while of low rating or normal voltage rating are considered to as ordinary / normal diode
