This fundamental item in electronics is very simple, and most do not need a large size.
But Mercury arc rectifiers occupy a good part of a m^3.
Thyristor rectifiers as used on HVDC grids, where the voltage may be +/- 250kV, and the power many MW, need some space to dissipate their heat.
What else can I help you with?
What are two types of diode?
Light Emitting Diode (LED) & the Avalanche Diode. These are two types of diodes ,but there are more
Why power diode has more power ratings?
It will be dissipating more power than a small signal diode.
Where is the automatic headlight sensor or diode located on a 1998 Olds Achieva?
you should see a small dome about the size of a dime on the dash somewhere and it will have a cloudy but see-through color.
How do you use a thyristor as a diode?
A thyristor, also known as a silicon controlled rectifier, is a diode that can be turned on by application of a small gate voltage.
What does the electronics term LED stand for?
It actually means Light Emitting Diode. I hoped i helped :)
When does the diode not allowed to flow the current?
A diode is a one-way gate for electrical current to flow through. You must have the right size diode for the amount of current that will be used in your circuit. The stripe on the diode is your output end. That is, the current must enter your diode at the non-stripe end and leave at the end with the stripe. This coincides with the diode symbol used on your schematic. If your diode is in backwards, the circuit will not work as the gate in the diode will block the current just the way it should.
Is 1N4007 OA79 silicon or germanium diode?
The entire 1N40xx series of power diodes are all silicon. The OA79 small signal diode is germanium.
Which is better as a switch diode or transistor?
Basically a diode is a combinstion of pN junction but the transistor is made with three terminals EMITTER,, BASE ,, JUNCTION.. and diode is just a combination of positive and negative terminal . diode and transistors are both used as a switch .. but a transistor is more widly udes than a diode. and diode has also very important in electronics DIGITAL SYSTEM to make the screen's ..and transistors are used in amplifiers the group of transistors make an amplifier . and we use a diode in seven segment display ....diode is small and carry less current due to its small size but transistor get large current. A2 A diode has two connections. It allows current to flow in one direction and not in the other. They are used for rectification in power supplies, detection of AM radio, blocking of current etc. A Transistor has three connections. Current is controlled between the emitter and collector, by a small current on the base. They are used as switches, amplifiers and regulators.
When is a laser diode module a useful thing to have?
A laser diode module is useful when a small laser with lower power usage is needed. The diode is used in a multitude of fields, including life science, industrial, and scientific instrumentation.
What is the I-V characteristic of a diode?
The I-V characteristic of a diode is a graphical representation of the relationship between the current (I) flowing through the diode and the voltage (V) across it. In the forward bias region, the diode allows current to flow with a small voltage drop once a threshold (the forward voltage) is exceeded, leading to an exponential increase in current. In reverse bias, the diode blocks current until a breakdown voltage is reached, where a small reverse current can occur. This characteristic illustrates the diode's ability to conduct electricity in one direction while preventing it in the other.
What will a Zener diode do at breakdown voltage?
A Zener Diode will continue to show its breakdown characteristics until it gets fried...for example a 5 volt zener will get fried at a breakdown voltage of about 6 volts..this happens because of the large amount of current flowing through the small diode which unfortunately the diode cannot handle.
When a 6 V zener diode is series with a 12 V zener diode what is the effect?
If they are both connected in the correct direction, and they are both rated for close to the same power dissipation (approx the same physical size), then you have created an 18-V zener diode.
