Forward current flow in a Schottky rectifier is due
to majority carrier conduction. S o r everse recovery
is not affected by s torage charge as in conventional
PN junction diodes.
Nevertheless, when the device switches from forward biased condition to reverse blocking state,
This current depends only of diode capacitance and
external circuit impedance. Satisfactory circuit behaviour analysis may be performed assuming that
Schottky rectifier consists of an ideal diode in parallel with a variable capacitance equal to the junction capacitance (see fig. 5 page 4/4).

current is required to charge the depletion capacitance of the diode.
