What is material made of a zener diode?
SILICON same as any other diode but with different characteristics
What sort of diode do you need when putting a solar cell on a battery powered device?
There are two basic types of diodes; Silicon and Germanium. I would use germanium because it has a lower forward bias than silicon. I suspect that what you really want to know is how to hook up an isolation diode. This is a diode that is installed in series with the alternate power source to isolate one from the other. Whether you use germanium or silicon the way that you want to hook it up is pretty straight-forward. go ahead and hook the negative (black) lead of the solar cell to the negative (black) lead of the battery. Hook up the positive (red) lead of the solar cell to the anode of the isolation diode and the cathode end of the diode hooks up to the positive (red) lead of the battery. You can identify the anode and cathode ends of the diode by looking on the diode - you will see a little diagram that looks like an arrow with a straight line at the tip of the arrow. the straight line side is the cathode end. Unless you have a really big solar panel you could probably use a general purpose diode such as a 1N4001 silicon (available at radio-shack)Hope this helped you.
Which type of diode used in bridge rectifier?
You can use most diodes for that purpose, and particularly silicon diodes. However, you should not use zener diodes and similar for rectification purposes. Otherwise, you will likely not get the intended result. If the voltage exceeds the avalanche voltage, then the zener diode will no longer rectify, but conduct the other way as well.
What is the difference between a semiconductor diode and a microwave diode?
The primary difference is that a semiconductor diode is a diode with a p-n junction, and a light-emitting diode is a special case or special type of semiconductor diode that emits light when it is forward biased.
Gold is diffused into silicon pn junction diode why?
In order to shorten the switching time, diodes sometimes are doped with gold or other deep-level impu- rities to create more generation centers and to increase the carrier recombination rate.

SILICON same as any other diode but with different characteristics
What is the voltage drop in diode IN4007?
forward drop is the same as any other silicon diode, about 0.7V
What is the forward voltage of a silicon based zener diode?
It would be 0.7V, the same as any other silicon diode; except for one thing, most zener diodes are manufactured with a reversed diode in series with them. When the zener is operated in its normal zener breakdown mode this reversed diode conducts, letting the zener operate. When the zener is operated in its forward biased mode this reversed diode prevents conduction. Thus most zeners have no forward voltage.

What does BY stand for in the name of the diode BY127?
The first letter B indicates what the diode is made of, i.e. B stands for Silicon, hence it is a Silicon diode in this case (it could have been a Germanium diode if the first letter was A instead of B). And the second letter, Y in this case stands for the function of the diode, i.e. Rectifier (As these diodes are often used in rectifier circuits). Other second alphabets could be A, B, or Z which stand for separate functions (which I don't remember at the moment).
What is pn junction diode?
It's a rectifier diode made simply by combining P type and N type silicon. Where the two are joined, forms a junction that allows conduction in one direction only. A pn junction diode is a diode obtained by by dopping a silicon crystal through the process of covalent bond.
Why silicon controlled rectifier doesn't work in reverse biased condition?
Because when reverse biased it behaves like any other rectifier/diode.

Power diode made up of?
Power diodes are made primarily of silicon, though small quantities of other materials, such as boron, gallium arsenide, germanium or phosphorous are also used.
What diode equation?
It is an equation that describes the I-V characteristic of a diode. In other words, how the current depends on the voltage.The Shockley diode equation uses an exponential expression. See the Wikipedia article on "Shockley diode equation" for more details. However, for many practical purposes, it's accurate enough to think of a diode as being "open" in the "forward" direction (no voltage drop), and having a voltage drop of about 0.7 V (in the case of diodes made from silicon) in the "reverse" direction.

Is a diode an insulator?
No. A diode conducts in one direction but not in the other.
