Use of the above model permits junction to lead thermal

resistance for any mounting configuration to be found. For

a given total lead length, lowest values occur when one side

of the rectifier is brought as close as possible to the heatsink.

NOTE 3. — 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 6)

efficiency

measurements

show

that

operation will be satisfactory up to several megahertz. For

example, relative waveform rectification efficiency is

approximately 70 percent at 2 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.
