photo diode donot work for long distance photo diode act as a receiver
A photodiode is a type of photodetector capable of converting light into either current or voltage, depending upon the mode of operation. Its characteristics is same as that of an ordinary diode, except that it depends on light.
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.
The 2N5777 is a Darlington silicon NPN photo detector, or, if you prefer a photoDarlington. A link is provided to a bit of data on this device.
zener diode
leakage current itself
the current in mosfet is controlled by electric field where as in poto diode is controlled by intensity of light
photo diode donot work for long distance photo diode act as a receiver
A Photo-diode is used to receive light. whereas the L.E.D. is a Light Emitting Diode.
the current which has negative value n passes through the diode is called as diode reverse current
The leakage current of a (zener) diode is the current that leaks when a diode is connected in reverse biased.

A photo diode
A silicon avalanche photo diode is fabricated by the process called impact ionization.

A diode is semiconductor device which is used in a lot of application in electronics equipment.it is negative temp. coefficient device i.e. at lower temp. it is behave like a insulator and high temp. it is work like a good conductor. Basically a diode is used to convert an alternating current into direct current in form of a rectifier. There are many types of diode used in today day to day life depends upon their application. 1 crystal diode 2 photo diode 3zener diode are some of the most useful diode.
