The current flow In a Schottky barrier rectifier Is due
to majority earner conduction and Is not affected by
reverse recovery transients due to stored charge and
minority carrier injection as in conventional PN
diodes.
The Schottky barrier rectifier may be considered for
purposes of circuit analysis, as an ideal diode in
parallel with a variable capacitance equal in value to
the junction capacitance. See Figure 3.
