When the diode is “on”, it acts as a short circuit and passes all current. La diode de roue libre doit supporter en courant le courant circulant dans l'inductance. Apart from Schottky Diode, rest of the diodes are made by forming P-type semiconductor to N-type semiconductor. The charge storage that limits the reverse recovery of junction diodes does not occur in schottky diodes and reverse recovery is very fast.

In the early days of thermionic valve (vacuum tube) manufacture, each manufacturer gave a number to the types they manufactured. It may be cheaper for the mfg to simply make 1N4007s and mark the poorer performing batches as 1N4001, 1N4002 etc, or even sell higher performing parts under the lower grade part number.
