Diode Types




Germanium Diode

That is made ​​of germanium bilateral
Injected through adulteration and be a positive crystal with impurities
Other crystallization be negative, so that
Positive and negative free sides where they
are adjoined.



Silico
DIDOE


This is the duo made ​​of silicon
Injected through adulteration and be a positive crystal with impurities
Other crystallization be negative, so that
Free sides where they positive and negative adjacent
.


Light Emitting
Diode LED :


Dual optical emission radiates
Light when electrical signal is raised.
And connected to a bilateral, but also in optical Navat
Figure in the direction of the front and theory is based
The work of this duo that electricity
E Almatta his work on the conduction front
Moving charge carriers which leads to generate
Free photons emitted in all directions, causing
Radiation light.
And always find resistance value between
680 ohms to 1 kilo ohm to protect the bilateral
Baath LED light


Photo Diode:

Of semi-conductor positive
P and N, and another negative transparent window for executing the light
As shown in Fig.

When light falls on the bilateral
Photosynthesis, the light broken links
Crystalline and freed a number of shipments
Called the shipments of the minority, this increase
Increase the number of light falling component
Tiara-called stream diversion is used in
Circuit
Consists of the future for bilateral Ldw
.

Varactor Diode:

Using capacitive diodes Kmktvat variable
Depending on the effort against them.




Tunnel Diode

Schotky Diode

Gun Diode
