Diodes are usually rated in amperage. A diode may be capable of handling only a 10th of an ampere. Some diodes called Power diodes may be capable of handling up to 100 amperes per diode. To select the proper diode, you must know what the maximum amperage your circuit is capable of. Then you would select one that would handle at least 120 percent of the amperage your circuit would handle.
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.
gunn diode is transfered electron device & PIN diode is semiconductor device
whether we know that p-n diode is real diode. But still in case of semeconductor we see then silics is real diode.
Bulk resistance of diode depends on how it is biased. The bulk resistance of a diode is the approximate resistance of the diode when it is forward biased.
One can purchase laser diode modules on select places around the Hong Kong. OPELUS is the best place to purchase laser diode Modules, Infrared Laser Module, Green Laser Module etc.
By figuring out how much amperage you wish to pass through the diode. If for instance you are building a battery charger and the transformer would normally supply 10 amps, you would select a diode (or diodes in parallel) that would handle at least 10 amps. You would normally select diodes that are at least 125% of the current desired. In this example you would select a diode that would handle at least 12.25 amps. It is better to use a rating of 150% for a safety margin.

by measuring the body size
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.
The 2014 Nissan Rogue-Select has a 2.5 L base engine size.
to select a random sample you pick them at random
zener diode :zener diode operates under reverse bias voltageideal diode :ideal diode operates under forward bias voltage
according to use
yes, diode can be used as rectifier diode to convert ac to dc
you try it on of corsebut you can just check the size
The read type diode are called impatt diode
