in
general, the working principle of diode is as formed of a semiconductor
construction with anode polarity (P) and cathode polarity (N) which
usually consists of geranium or silicon were combined, and the charge of
type N is a material with an excess of electrons, and the charge of
type P composed
of materials with a shortage of electrons which are separated by the
depletion layer caused by the balance of the charge, therefore the diode
produces a hole that serves as a carrier so that the voltage or charge
transfer occurs once the drainage flows occurring in the hole that
generates direct current voltage or commonly referred to as DC.

Working
Principle of Diodes variance with the principle or theory of electrons
which states that an electric current that occurs due to the movement of
electrons from the positive pole toward the negative pole, but this
diode current flow in one direction only, ie DC voltage. Therefore,
if the diode is fed by a voltage P greater than the charge N, then the
electrons contained in the N charge will flow to the load P is referred
to as Forward Bias, and vice versa, ie if the diode is fed with a
voltage greater N than the voltage P, then the electron is in it will not move, so the
diode does not flow through any charge, the condition is often referred
to as a reverse bias.

from
the above explanation can be concluded that the Working Principle of diode
is one tool that is very unique because it is able to manipulate the
charge to be unidirectional or DC loads. The
connection between the anode load (P) with cathode load (N) is called a
depletion layer (depletion layer) where there is a balance of electron
and hole charge. Usually
on the side of the P lot formed hole-hole ready to accept the charge of
the electron, whereas the N side many electrons are ready to liberate
themselves, in other words if the P given the potential charge more,
then the electrons from the N side will immediately fill every hole- hole in the side of P.
