NOTE 4 — HIGH FREQUENCY OPERATION

Since current flow in a Schottky rectifier is the result of majority

carrier conduction, it is not subject to junction diode forward and

reverse recovery transients due to minority carrier injection and

stored charge. Satisfactory circuit analysis work may be performed

by using a model consisting of an ideal diode in parallel with a

variable capacitance. (See Figure 11.)
