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 10.)
700
500
Rectification efficiency measurements show that operation will
be satisfactory up to several megahertz. For example, relative
waveform rectification efficiency is approximately 70 percent at
2.0 MHz, e.g., the ratio of dc power to RMS power in the load is
0.28 at this frequency, whereas perfect rectification would yield
0.406 for sine wave inputs. However, in contrast to ordinary
junction diodes, the loss in waveform efficiency is not indicative of
power loss; it is simply a result of reverse current flow through the
diode capacitance, which lowers the dc output voltage.

GUARDRING
Motorola builds quality and reliability into its Schottky Rectifiers.
First is the chip, which has an interface metal between the
barrier metal and aluminum–contact metal to eliminate any
possible interaction between the two. The indicated guardring
prevents dv/dt problems, so snubbers are not mandatory. The
guardring also operates like a zener to absorb over–voltage
transients.

rated per UL 94, V0 @ 1/8″. Wire bonds are 100% tested in
assembly as they are made.
Third is the electrical testing, which includes 100% dv/dt at 1600
V/ s and reverse avalanche as part of device characterization.
