Your question is not completely clear, but I'm going to guess what you might want. Here is a list of various types of devices that are/were used as diodes:
- galena (lead sulfide) cat's whisker detector
- vacuum tube diode
- gas filled diode
- copper oxide rectifier
- selenium rectifier
- cavity magnetron (specially constructed vacuum tube diode that acts as a microwave oscillator)
- germanium point contact diode
- germanium junction diode
- silicon junction diode
- varactor diode (voltage controlled variable capacitor)
- zener diode (reverse breakdown regulator)
- avalanche diode (surge protector, etc.)
- IMPATT diode (microwave negative resistance amplifier)
- metal-semiconductor junction (schottky) diode
- shockley diode (threshold trigger)
- photodiode (light sensor)
- tunnel diode (negative resistance amplifier)
- various types of light emitting diodes
- various types of LASER diodes
- silicon solar cells
- gallium arsenide solar cells
- etc.
There are also a wide variety of two terminal devicesthat can be referred to as diodes, but can conduct in either direction:
- neon lamps
- neon lights/signs
- cold cathode fluorescent lamps
- Mercury vapor street lights
- high & low pressure sodium vapor street lights
- geiger-mueller tube
- xenon HID vehicle headlight bulbs
- gunn diode (microwave negative resistance amplifier)
- PIN diode
- etc.
What else can I help you with?
What devices is used to absorb unwanted voltage fluctuations in a circuit?
diode
Can a diode be used as rectifier diode?
yes, diode can be used as rectifier diode to convert ac to dc
What is power diode generally made from?
As that of most power devices power diode are maid from silicon material(because of its wide band gap) . but now days alloy of silicon are used like sic(silicon carbide) by ank
What is the purpose of diode?
Diode is a generic name for many different electronic devices that have 2 electrical connections. The most common one (rectifier diode) will let current through in one direction, but not in the other, but several other "diodes" exist, like the Zener diode that absorbs excess voltage, or the light emitting diode that emits light. Some common devices, such as a a resistance, also have 2 connections but are not traditionally called a "diode". A diode can also be used as a clamp, and as a detector (mixer) in an a.m. receiver.
Is it pn junction diode used as voltage regulator?
zener diode
What type of diode is often used in television remote-control devices?
infrared diode
What devices is used to absorb unwanted voltage fluctuations in a circuit?
diode
What are materials which are suitable for electronic devices?
there are several type of electronics devices and several type of material used for these devices but material which is used for device should able to full fill the requirement of that device. for instance rectifier diode - Silicon Photo Diode - Germanium High Frequency devices - GaAs, InGaAs, GaP etc. Every material has it's own configuration so conclusion is that any one semiconductor material can not used as universal material for all semiconductor devices.
Can a diode be used as rectifier diode?
yes, diode can be used as rectifier diode to convert ac to dc
What is the Structure of LCD and LED?
LCD is liquid crystal display, used in computer monitors and handheld devices; LED is a light emitting diode, and are used in some TV's and devices. LED's are the small, bright lights, like a camera or phone flashlight.
What are the active electronic components?
Active devices are those devices which can produce power or which can amplify the signal Such devices are- diode transistor op-amp
What is the characteristic of a diode when electrical current passes through it?
A "diode" is any of several devices; the only thing they have in common is that they have two electrical connections - hence the name. These devices have different functions. The simplest semiconductor diode, and one of the most common, is probably the rectifier diode. It lets current pass in one direction, but not in the other direction.
What is the function of diode what is the function of diode?
A diode is used primarily as a Rectifier
What are the four materials used in electronics?
There are several types of material which are used for different -2 circumstances in electronics engineering domain.Widely used semiconductors are- Silicon - for diode ,solar cell, BJT etc. germanium- for photo devices,and BJT for low level signal amplification. GaAs(Gallium Arsenide)- for high frequency devices like tunnel diode Gunn diode. InP & AlGaAs- for LED and others semiconductor material are also available like CdS,SiO2,GaP etc.
What kind of a light source is light emitting diode?
The so-called LED light emitting diode is a semi-conductor light source. It is mainly used as a light indicator on many devices. It is also found in many applications.
What is power diode generally made from?
As that of most power devices power diode are maid from silicon material(because of its wide band gap) . but now days alloy of silicon are used like sic(silicon carbide) by ank
How may type of resistors in diode?
None. A diode does not have a resistor in it. Diodes and resistors are different devices used for different purposes. For example, increasing current flow through a resistor increases the voltage drop across the resistor. Increasing current flow through a diode (within the diode's capabilities, just the same as a resistor) will actually decrease the voltage drop across the diode (once the diode "turns on" this voltage variance will be fairly small, though).
