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 heat sink.
Terms in the model signify:
TA = Ambient Temperature TC = Case Temperature
TL = Lead Temperature TJ = Junction Temperature
RθS = Thermal Resistance, Heat Sink to Ambient

(Subscripts A and K refer to anode and cathode sides,
respectively.) Values for thermal resistance components are:
RθL = 100°C/W/in typically and 120°C/W/in maximum.
RθJ = 36°C/W typically and 46°C/W maximum.
NOTE 5 — HIGH FREQUENCY OPERATION:
Since current flow in a Schottky rectifier is the result of ma-
jority carrier conduction, it is not subject to junction diode for-
ward 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.)
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 MHz, e.g., the ratio of dc power to RMS power in
the load is 0.28 at this frequency, whereas perfect rectifica-
tion would yield 0.406 for sine wave inputs. However, in con-
trast to ordinary junction diodes, the loss in waveform effi-
ciency 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.
