Operation [Edit]
A PIN diode operates under what is known as high-level injection. In, other words the intrinsic "I region." Is flooded with charge carriers from the "P" and "n" regions. Its function can be likened to filling up a water bucket with. A hole on the side. Once the water reaches the hole 's level it will begin to pour, Similarly out.The diode will conduct current once the flooded electrons and holes reach an, equilibrium point where the number of electrons. Is equal to the number of holes in the intrinsic region. When the diode is forward biased the injected, carrier concentration. Is typically several orders of magnitude higher than the intrinsic level carrier concentration. Due to this high, level injectionWhich in turn is due to the, depletion process the electric field extends deeply (almost the entire length) into the, region. This electric field helps in speeding up of the transport of charge carriers from P to, N region which results in faster. Operation of the diode making it, a suitable device for high frequency operations.
