Axial Lead Rectifiers
. . . employing the Schottky Barrier principle in a large area metal–to–silicon
power diode. State–of–the–art geometry features chrome barrier metal,
epitaxial construction with oxide passivation and metal overlap contact. Ideally
suited for use as rectifiers in low–voltage, high–frequency inverters, free
wheeling diodes, and polarity protection diodes.

Designer’s Data for “Worst Case” Conditions — The Designer’s Data Sheet permits the design of most circuits entirely from the information presented. SOA Limit
curves — representing boundaries on device characteristics — are given to facilitate “worst case” design.
Preferred devices are Motorola recommended choices for future use and best overall value.

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.)
