NOTE 6 — 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 minor-

ity carrier injection and stored charge. Satisfactory circuit

analysis work may be performed by using a model consist-

ing of an ideal diode in parallel with a variable capacitance.

(See Figure 10.)
